Seismologists are often asked the question, Can large earthquakes trigger volcanic eruptions? The short answer is yes, earthquakes and volcanic processes are closely linked, as suggested by the existence of the ring of fire of active volcanoes and earthquakes circling the Pacific Ocean.. A volcanic eruption occurs when the force of the magma plumbing system exceeds the force holding the rock together between the magma chamber and the surface. For earthquakes that are relatively close to an active volcano, the displacement of the earthquake itself can change the stresses around the magma chamber, possibly bringing the volcano closer to an eruption. Depending on the type of earthquake and the geometry of the fault, different areas around the earthquake source area may be subject to increased compression or relaxation. A nearby magma chamber that experiences relaxation of the crust above the chamber as a result of a large nearby earthquake would be more likely to erupt because less force would ...
Landslides and rock avalanches triggered by the 2008 Wenchuan Earthquake produced 257 landslide dams, mainly situated along the eastern boundary of the Qinghai-Tibet Plateau where rivers descend approximately 3,000 m into the Sichuan Basin. The largest of these dams blocked the Tongkou River (a tributary of the Fujiang River) at Tangjiashan. The blockage, consisting of 2. 04 ?? 10 7 m 3 of landslide debris, impounded a lake with a projected maximum volume of 3. 15 ?? 10 8 m 3, potentially inundating 8. 92 km 2 of terrain. Its creation during the rainy season and the possibility of an uncontrolled release posed a serious, impending threat to at least 1. 3 million people downstream that could add substantially to the total of 69,200 individuals directly killed by the earthquake. Risk assessment of the blockage indicated that it was unlikely to collapse suddenly, and that...

Distribution of the aftershocks magnitude 4+ since the main quake (as of April 9, 2018). The size and colour (small to large, yellow to red) indicate aftershock magnitude and D+ the number of days after main shock. The white shaded ellipse represents the area of greatest slip during the main shock. Green diamonds represent the main gas fields. USGS/Gilles Brocard, Author providedIt is this tectonic activity that determines the delicate interplay of economic benefits from raw materials, and the often-devastating and usually-unpredictable effects of natural disasters on society.. Although the February earthquake occurred at the very heart of one of the largest and newest gas fields in the country, the industrial installations, at the highest international standards, have not suffered major damage from the tremors.. But the ongoing disaster triggered a temporary halt in gas extraction, as the facilities require inspections and repairs. Unfortunately, and unusually, the earthquakes have struck in ...
BY CATHERINE YESAYAN. On Wednesday morning, on December 7, 1988, Armenians around the world woke up to the horrific news of the earthquake that hit and ravaged the two cities of Gyumri and Spitak and caused at least 25,000 souls to perish and shook Armenia and its diaspora to the core.. The earthquake was estimated to have had a magnitude of at least 6.8 on the Richter scale. The forceful rattle, combined with the poor quality of the communist era construction, caused an unprecedented devastation that its scars still show today after 30 years.. For those who were there when the shock occurred and rattled the region, 11:41am, the moment that the earthquake hit, is permanently engraved on their minds. In no time, the world started to pour money and all kinds of aid to the victims of the earthquake.. In July of 2012, twenty-four years after the earthquake, we, three friends and a tour guide, criss-crossed Armenia and re-discovered many sights. It was then that for the first time, I visited Gyumri, ...
Although only centimeters in amplitude over the open ocean, tsunamis can generate appreciable wave amplitudes in the upper atmosphere, including the naturally occurring chemiluminescent airglow layers, due to the exponential decrease in density with altitude. Here, we present the first observation of the airglow tsunami signature, resulting from the 11 March 2011 Tohoku earthquake off the eastern coast of Japan. These images are taken using a wide‐angle camera system located at the top of the Haleakala Volcano on Maui, Hawaii. They are correlated with GPS measurements of the total electron content from Hawaii GPS stations and the Jason‐1 satellite. We find waves propagating in the airglow layer from the direction of the earthquake epicenter with a velocity that matches that of the ocean tsunami. The first ionospheric signature precedes the modeled ocean tsunami generated by the main shock by approximately one hour. These results demonstrate the utility of monitoring the Earths airglow layers for
YELLOWSTONE - The U.S. Geological Survey reported a 3.0-magnitude earthquake occurred at 5 p.m., Monday, May 18th near the Old Faithful Geyser in Yellowstone National Park (click here for USGS summary). Several people reported feeling this seismic event. While earthquakes are common in Yellowstone these events have also occurred in other areas of the state.. In 2014, the Wyoming State Geological Survey reported 49 earthquakes with magnitudes greater than 2.5 occurred in Wyoming. Twenty of those had magnitudes greater than 3.0, with 17 of these events recorded in Yellowstone. The largest earthquake in 2014 was 4.8 in magnitude near Norris Geyser Basin in the park. ...
As well known the influence on Earth is not determined by the solar radiation parameters but is determined by parameters of absorbed radiation. Therefore the correlation mechanism of solar activity and seismic activity has not been fully defined. First-ever, on the bursts of solar activity, reacts ionosphere. The results of the study [19] show some unusual perturbations observed in 1-25 days before and 2-3 days after the main shock of every earthquake indicating a clear seismo-ionospheric link and may be used as earthquake precursors. Such subionospheric plasma irregularities have been observed by satellites prior to seismic activity electric and magnetic field perturbations in the upper ionosphere [20]. The final results showed that the ionospheric vertical total electron content around the epicenter of earthquake in China (May 12, 2008), increased obviously 9 days before the earthquake, decreased significantly 6 days before the earthquake and increased strikingly 3 days before the earthquake. ...
On the 21st of November 2004 the islands of Dominica & Guadeloupe were struck by an Earthquake measuring 6.3 on the Richter scale and an aftershock of 4.8. Since then the north of the island has been racked by numerous tremors seemingly associated with the initial event.. In the north of the island was hardest hit. The 150 year old Catholic church which dominated the skyline of the town of Portsmouth was demolished by the quake. Several other buildings suffered structural damage throughout the north of the island.. Schools and other structures including the Portsmouth Hospital have been abandoned pending inspections to determine the structural integrity of those buildings. This website was created in the aftermath of these events in an effort to inform the many Dominicans on Dominica and overseas of the impact of these Earthquakes on our country.. Please view the photo album on this site in for pictures of the aftermath 21/11/04.. A daily record of all earthquakes is kept at this site. ...
The Great East Japan Earthquake that occurred on March 11, 2011, and subsequently occurring Fukushima Daiichi Nuclear Power Plant accident caused tremendously serious damage and left a long-lasting emotional scar on the Japanese people. In particular, the power plant accident thrust upon us the fundamental question Who owns the information? The people were confused at that time since many evacuees were exposed to needless radiation because the government did not disclose information immediately after the accident or since various specialists spoke about the radiation exposure from different positions. Even now, one cannot say that the government or Tokyo Electric Power Company (TEPCO) has fulfilled their accountability to the Japanese people regarding the cause of the accident. Now about four years have passed since the accident. We still have 230 thousand or more evacuees (as of December 2014) and a polluted water problem. However, the accident has started to fade from many peoples memory. ...
A subterranean ice wall surrounding the nuclear reactors at the stricken Fukushima No. 1 Nuclear Power Plant to block groundwater from flowing in and out of the plant buildings has approached completion. Initially, the ice wall was lauded as a trump card in controlling radioactively contaminated water at the plant in Fukushima Prefecture, which was crippled by meltdowns in the wake of the March 2011 Great East Japan Earthquake and tsunami. But while 34.5 billion yen from government coffers has already been invested in the wall, doubts remain about its effectiveness. Meanwhile, the issue of water contamination looms over decommissioning work. In a news conference at the end of July, Naohiro Masuda, president and chief decommissioning officer of Fukushima Daiichi Decontamination & Decommissioning Engineering Co., stated, We feel that the ice wall is becoming quite effective. However, he had no articulate answer when pressed for concrete details, stating, I cant…. ...
At least a dozen nuclear power plants have shut down across the country and millions of buildings around Tokyo were left without power from the Japan earthquake.
We present two models for estimating the probabilities of future earthquakes in California, to be tested in the Collaboratory for the Study of Earthquake Predictability (CSEP). The first, time-independent model, modified from Helmstetter et al (2007), provides five-year forecasts for magnitudes m , 4.95. We show that large quakes occur on average near the locations of small m , 2 events, so that a high-resolution estimate of the spatial distribution of future large quakes is obtained from the locations of the numerous small events. We employ an adaptive spatial kernel of optimized bandwidth and assume a universal, tapered Gutenberg-Richter distribution. In retrospective tests, we show that no Poisson forecast could capture the observed variability. We therefore also test forecasts using a negative binomial distribution for the number of events. We modify existing likelihood-based tests to better evaluate the spatial forecast. Our time-dependent model, an Epidemic Type Aftershock Sequence (ETAS) ...
On November 14, 2011,the Institute for Global Environmental Strategies (IGES) released the results of an international survey on energy and climate change policies in Japan after the Great East Japan Earthquake and the Fukushima nuclear plant accident. The survey targeted experts and researchers who are deeply interested in global energy and environmental issues: 710 respondents answered the survey (Japanese 61%, non-Japanese 39%). Asked about nuclear power plant and energy policies in Japan, about 49% responded that Japan should shut down nuclear power plants and start the process of decommissioning operating plants within 1 to 2 year or by 2020. About 83% supported some form of a phase down, including a more gradual decommissioning concluding in 2050.. ...
The best seismologists in the world dont know when the next big earthquake will hit. But a Tel Aviv University geologist suggests that earthquake patterns recorded in historical documents of Middle Eastern countries indicate that the regions next significant quake is long overdue.. A major quake of magnitude seven on the Richter scale in the politically-fragile region of the Middle East could have dire consequences for precious holy sites and even world peace, says Tel Aviv University geologist Dr. Shmulik Marco. In light of this imminent danger, Marco, from the schools Department of Geophysics and Planetary Sciences, has taken an historical approach to earthquake forecasting by using ancient records from the Vatican and other religious sources in his assessment. The past holds the key to the future, he says.. All of us in the region should be worried, explains Marco, who dedicates his career to piecing together ancient clues.. Based on the translations of hundreds of documents -- some of ...

Chinese state media say an aftershock has occurred at a lake formed by last months earthquake and that the growing body of water is threatening to flood thousands of homes downstream. Xinhua news says the aftershock of 4.8 magnitude struck the southwestern province of Sichuan Sunday, causing massive landslides on mountains surrounding the lake. It says the aftershocks impact on the threatened area is under surveillance. Earlier today, Xinhua said the lake is still rising dangerously despite efforts to drain the water safely. Xinhua news agency quoted provincial official Zhang Ting as
An earthquake is the shaking and vibration at the surface of the Earth caused by underground movement along a fault line plane or by volcanic activity. Most earthquake casualties result from falling objects or debris when shocks damage or demolish buildings and other structures. Electricity and telephone lines, gas, sewer and water mains can also be damaged.. Earthquakes can also cause a tsunami, or a series of waves which can cross an ocean and cause extensive damage to coastal regions. In areas where there are steep slopes, vibrations resulting from earthquakes may cause landslides.. Any part of Australia could experience an earthquake and there is no accepted method to predict earthquakes. Parts of South Australia, including Adelaide and the mid-north are earthquake hazard areas with a high potential for future earthquakes. The Eden-Burnside Fault Zone (composed of several different individual faults) lies at the base of the main scarp of the Adelaide Hills. It begins around One Tree Hill in ...
The grandeur of citywide reconstruction schemes required investment from Eastern monetary sources, hence the spin and de-emphasis of the earthquake, the promulgation of the tough new building codes, and subsequent reputation sensitive actions such as the official low death toll. One of the more famous and ambitious plans came from famed urban planner Daniel Burnham. His bold plan called for, among other proposals, Haussmann-style avenues, boulevards, arterial thoroughfares that radiated across the city, a massive civic center complex with classical structures, and what would have been the largest urban park in the world, stretching from Twin Peaks to Lake Merced with a large atheneum at its peak. But this plan was dismissed during the aftermath of the earthquake.. The earthquake also was crucial in the development of the University of California, San Francisco and its medical facilities. Until 1906, the school faculty had provided care at the City-County Hospital (San Francisco General Hospital, ...
A 4.9 magnitude earthquake struck 10 km south-east of Borazjan, Iran, at 2.20am GMT according to USGS.Reports said the quake hit near a nuclear plant, but added that it was a natural event.The world was shaken by the news of Iranian missiles hitting Iraqi bases housing US-led coalition personnel, and the crash of a Ukrainian passenger jet shortly after take-off from Tehrans
The 2015 Sabah earthquake (Malay: Gempa Bumi Sabah 2015) struck Ranau, Sabah, Malaysia with a moment magnitude of 6.0 on 5 June, which lasted for 30 seconds. The earthquake was the strongest to affect Malaysia since 1976. Eighteen people died on Mount Kinabalu, with most of the deaths being members of a group from Tanjong Katong Primary School while about 137 other people who were climbing the mountain were stranded, but were subsequently rescued. Tremors were also felt in Tambunan, Tuaran, Kota Kinabalu, Inanam, Kota Belud, Kota Marudu, Kudat, Likas, Penampang, Putatan, Kinarut, Papar, Beaufort, Keningau, Beluran, Sandakan, Kunak, Tawau in Sabah and as far afield as Federal Territory of Labuan, Lawas, Limbang and Miri in Sarawak as well as Bandar Seri Begawan in Brunei. As a result of the earthquake, most areas in the Kinabalu Park have been closed temporarily until the situation is cleared and undergoing repairs and rehabilitation. Sabah lies within the Sunda Plate away from any plate ...
Accelerograms obtained at two sites during the San Fernando earthquake of 1971 were analyzed to investigate the role of soil-structure interaction, using techniques developed by Bielak and others. Analysis of the data from the site of the Hollywood Storage Building, for which data from the Arvin-Tehachapi earthquake of 1952 are also available, showed evidence of soil-structure interaction in the way the transfer functions between parking lot and basement motion decayed with increasing frequency in the two lateral directions. It is concluded also that interaction probably had a small effect on the response near the EW fundamental frequency during the San Fernando earthquake. Although theoretical and experimentally determined transfer functions are broadly similar, they do not agree in detail. The lack of good agreement for reasonable choices of the parameters of the theoretical model indicates a need for some modifications of the theory or its application, and a need for more measurements at the ...

After the court decided the arrest was lawful and ordered Aliaj to appear before court twice a months until a final decision on her case, Rama went on Twitter:. Throughout the period of the natural disaster state of emergency, Japan puts in place extreme measures on private media, which apparently even in the Japan of old wisdom are a burden atop of the great earthquake burden! Dont make us do what even your imagination could not fathom!. Since the earthquake struck Albania on November 26, the prime minister has announced and continuously claimed afterwards that he has enacted a state of emergency (gjendje e jashtezakonshme - extraordinary state). The Albanian constitution stipulates that this particular kind of state of emergency, which foresees stronger measures than the state of natural disaster the government has actually enacted, must be declared by parliament.. It is not clear how the Albanian Constitution compares to the Japanese legislation mentioned in prime ministers tweet, and ...

A powerful earthquake struck western China on May 12, 2008, toppling thousands of homes, factories, and offices, trapping students in schools, and killing at least 10,000 people, the countrys worst natural disaster in three decades. The quake, which was estimated preliminarily to have had a magnitude of 7.9, ravaged a mountainous region outside Chengdu, capital of Sichuan Province, just after lunchtime, destroying 80 percent of structures in some of the towns and small cities near its epicenter, Chinese officials said. Its tremors were felt as far away as Vietnam and set off another smaller quake in the outskirts of Beijing, 900 miles away. Landslides, power outages and fallen mobile phone towers left much of the affected area cut off from the outside world and limited information about the damage. But snapshots of concentrated devastation suggested that the death toll could rise markedly as rescuers reach the most heavily damaged areas.The powerful initial quake struck at 2:28 p.m. near ...

A network of low frequency electromagnetic detectors has been operating in Central Italy for more than three years, consisting of identical instruments that continuously record the electrical components of the electromagnetic field, ranging from a few Hz to tens of kHz. These signals are analyzed in real time and their power spectrum contents and time/frequency data are available online. To date, specific interest has been devoted to searching for any possible electromagnetic features which correlate with seismic activity in the same region. In this study, spectral analysis has evidenced very distinct power spectrum signatures that increased in intensity when strong seismic activity occurred near the stations of the 2009 LAquila earthquake. These signatures have revealed horizontally oriented electric fields, between 20 Hz to 400 Hz, lasting from several minutes to up to two hours. Their power intensities have been found to be about 1 μV/m. Moreover, a large number of man-made signals and meteorologic
The Mw7.0 2016 Kumamoto earthquake occurred on the previously mapped Futagawa-Hinagu fault causing significant strong ground motions. A ~ 30-km-long dextral surface rupture appeared on the major fault zone and dextral slip was up to 2-3 m. However, the surface ruptures were also broadly and remotely distributed approximately 10 km away from the primary rupture zone. These numerous distributed secondary surface slips with vertical displacement of less than a few tens of centimeters were detected by the interferometric synthetic aperture radar (InSAR) technology in previous studies. Such displacements occurred not only on previously mapped faults but also on unknown traces. Here, we addressed the following fundamental issues: whether the broadly distributed faults were involved in the past major earthquakes in the neighborhood, and how the fault topography of such secondary faults develops, seismically or aseismically. To find clues for understanding these issues, we show the results of field measurements
The static Coulomb stress hypothesis is a widely known physical mechanism for earthquake triggering, and thus a prime candidate for physics-based Operational Earthquake Forecasting (OEF). However, the forecast skill of Coulomb-based seismicity models remains controversial, especially in comparison to empirical statistical models. A previous evaluation by the Collaboratory for the Study of Earthquake Predictability (CSEP) concluded that a suite of Coulomb-based seismicity models were less informative than empirical models during the aftershock sequence of the 1992 $M_w7.3$ Landers, California, earthquake. Recently, a new generation of Coulomb-based and Coulomb/statistical hybrid models were developed that account better for uncertainties and secondary stress sources. Here, we report on the performance of this new suite of models in comparison to empirical Epidemic Type Aftershock Sequences (ETAS) models during the 2010-2012 Canterbury, New Zealand, earthquake sequence. Comprising the 2010 $M 7.1$ ...
After the earthquake Strangers nod to each other As if family. a haiku. On March 11, the northeast coast of Japan suffered a magnitude-9.0 earthquake and destructive tsunami, resulting in the deaths of 5,178 people to date, more than 8,600 missing and the evacuation of 380,000 Japanese from the devastated areas. Many have been left homeless in freezing weather with limited food, water and electricity.. While the MGH and other hospitals await the call for medical assistance from the Japanese government, three MGH Emergency Services physicians already have traveled to the country to offer their support. N. Stuart Harris Jr., MD, MFA, FACEP, director of the Wilderness Medicine Fellowship of the Emergency Department; Takashi Shiga, MD, Emergency Medicine fellow; and Kohei Hasegawa, MD, Emergency Medicine resident, arrived in Tokyo on March 14 to work with the Disaster Medical Assistance Team of the Tokushukai Hospital Group..

Today, exactly one month after northern Japan was shaken by the 9.0-magnitude quake, a 6.6 magnitude aftershock rattled the same area around Fukushima. A warning for a 3-foot tsunami was issued after the temblor hit the northeast coast 5:16 p.m. local time, ABC News is reporting. The latest quake was reported to cause landslides in the city of Iwaki, including one that buried three houses and trapped four people inside, police in Fukushima Prefecture told CNN News. Attempts to rescue the families were ongoing, their condition was not immediately known, The office of Prime Minister Naoto Kan delayed a scheduled news conference due to the latest developments, his office said. Officials want to have the immediate situation under control before holding a news conference, the office said.. All advisories and warnings were lifted about an hour later, according to local Japanese TV.. The aftershock was originally reported to be 7.1 but was corrected to 7.0 by Japanese officials. The US Geological ...
As one of the causative agents of viral hepatitis, hepatitis E virus (HEV) has gained public health attention globally. HEV epidemics occur in developing countries, associated with faecal contamination of water and poor sanitation. In industrialised nations, HEV infections are associated with travel to countries endemic for HEV, however, autochthonous infections, mainly through zoonotic transmission, are increasingly being reported. HEV can also be transmitted by blood transfusion. Nepal has experienced a number of HEV outbreaks, and recent earthquakes resulted in predictions raising the risk of an HEV outbreak to very high. This study aimed to measure HEV exposure in Nepalese blood donors after large earthquakes. Samples (n = 1,845) were collected from blood donors from Kathmandu, Chitwan, Bhaktapur and Kavre. Demographic details, including age and sex along with possible risk factors associated with HEV exposure were collected via a study-specific questionnaire. Samples were tested for HEV IgM, IgG

The Special Publication No. 114 (Stickney et.al., 2000) map displays faults, earthquakes, and topography in western Montana. Funded through the Earthquake Hazards Reduction Program, the U.S. Geological Survey (USGS) compiled Quaternary faults in western Montana as part of a larger effort sponsored by the International Lithosphere Program. The USGS conducted a detailed review of published and unpublished maps and literature concerning Quaternary faults in western Montana. Fault data were entered into a data base and used to compile a map showing the locations, ages, and estimated slip rates of Quaternary faulting in western Montana. Fault traces were taken from original sources and compiled on 1:250,000-scale quadrangle base maps and digitized for use with the GIS. In addition to location and style of faulting, the data characterize the time of most recent movement and estimated slip rate for each fault. Also included are geographic and other paleoseismologic parameters and a bibliographic ...
The moment magnitude (Mw) 5.8 Mineral, Virginia, earthquake of 23 August 2011, was centered ~130 km south-southwest of Washington, D.C. (USA), and caused minor damage across Virginia and the Washington metropolitan area. The Washington Monument sustained masonry damage; a post-earthquake survey of the monument performed for the National Park Service identified cracking and spalling of the pyramidion (the topmost piece of the obelisk), and cracking, spalling, and lesser damage over the entire length of the monument shaft. A seismic vulnerability assessment of the monument was then performed to evaluate the potential for damage to the monument from future earthquakes. No ground-motion recordings of the Mineral earthquake were available for the monument site; therefore, deterministic and probabilistic seismic hazard analyses were performed to develop site-specific response spectra representing the Mineral earthquake and the maximum considered earthquake (MCE). These spectra were initially developed ...

ESA Sentinel-1A has added yet another string to its bow. Radar images from this fledgling satellite have been used to map the rupture caused by the biggest earthquake that has shaken northern California in 25 years.. Scientists collaborating through the UK Natural Environment Research Councils Centre for the Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET), used Sentinel-1As special capabilities to analyze the quake.. Synthetic aperture radar interferometry is a technique where two or more satellite radar images of the same area are combined to detect large-scale surface changes. Small changes on the ground modify the reflected radar signal and lead to rainbow-colored fringes in the interferogram.. Yngvar Larsen from Norways Northern Research Institute and Petar Marinkovic from PPO.labs in the Netherlands processed this new interferogram from two images: one that Sentinel-1A acquired on 7 August, the day the satellite reached its operational orbit, and another ...

Tsunami warnings issued after a 7.9 magnitude earthquake struck off Papua New Guinea on Saturday night have been canceled, the Pacific Tsunami Warning Center and New Zealand government said.
Constraining the date of the last major event occurred in a fault is of paramount importance in probabilistic seismic hazard assessment when time-dependent models are considered. Eight of the twelve destructive earthquakes occurred in the eastern Betic Cordillera since sixteenth century, are located less than 10 km away from the Alhama de Murcia fault (AMF). Up to now, it has not been identified any geological evidence on the ground surface to associate these events with the activity of specific fault sections of the AMF. In this work we present the first geological evidence of the catastrophic 1674 event occurred at Lorca (SE Spain). The excavations carried out at La Torrecilla Creek exposed archaeological remains from the Islamic period (VIII-XIII centuries in this region) affected by 55 ± 20 cm offset by the AMF fault. This event reached intensity VIII and produced 30 fatalities at Lorca for an estimated population of 7300 inhabitants. This supports the occurrence of earthquakes with surface ...
Scientists have issued a dire warning that the damaged Fukushima nuclear plant is at risk of a massive new earthquake.. Research using data from more than 6,000 recent tremors has found that last Marchs disaster has reactivated a seismic fault practically beneath the power station.. Now scientists are telling Japanese authorities to urgently shore up the damaged reactor in expectation of more massive quakes. Fukushima Daiichi was the scene of the worst nuclear disasters in history after it was damaged by the March 11, 2011, magnitude 9 earthquake and following tsunami.. But this tremors epicentre was about 100 miles from the site, off the coast of Japan, and a much closer one could occur in the future at Fukushima.. Dapeng Zhao, geophysics professor at Japans Tohoku University, said: There are a few active faults in the nuclear power plant area, and our results show the existence of similar structural anomalies under both the Iwaki and the Fukushima Daiichi areas.. Given that a large ...
An Earthquake That Shakes Our Hearts To Have A Stronger Faith! sermon, An Earthquake That Shakes Our Hearts To Have A Stronger Faith! sermon by John Wright takes you through - Matthew 27:50-54 Faith General sermons
Because Japan has historically suffered the most tsunamis, it is only natural that Japan would be the first country to develop a tsunami warning system. Japans development of tsunami science began in 1896 when a giant Sanriku tsunami, with run-up heights up to 38 m, claimed 22 000 lives. According to Shuto & Fujima [9], an article published in Japanese by an earthquake research group about the 1896 Sanriku tsunami identified an earthquake as the tsunami generator. Following this publication, there was an intense debate about the 1896 tsunami generation mechanism because of the extremely weak ground-shaking. Earthquakes of that type (weak shaking accompanied by strong tsunami) were later called tsunami earthquakes, and had become a major problem of all tsunami warning systems based on seismic measurements. Many researchers challenged the earthquake source hypothesis by proposing alternative mechanisms of an underwater volcanic eruption or landslide generators. Tsunami data recorded on a tide ...
Ten years ago, Japan was struck by the strongest earthquake in its recorded history, triggering a tsunami that killed more than 18,000 people and a meltdown at the Fukushima Daiichi nuclear power plant. But incredibly, the magnitude-9 tremour caused limited damage, in large part due to the countrys earthquake-resistant buildings. Our Japan correspondents report on how people in one of the most seismically active countries in the world are continuing to prepare for even the strongest quakes.

Korean dancer Kim Sun-ja, who resides in Japan, performs jinhonmu, a dance for the repose of the deceased. (Sep.1/2021, Tokyo ...
A pathetic man carrying a canary in a cage . . . a woman screaming frantically as she tore at the rubble of what had once been her home. These were among the survivors of an earthquake which shattered the city of Skopje in the south of Yugoslavia on 26th July, 1963.. It had begun with a dull rumble as the earths crust began to split, displacing tons of rock beneath the surface. As the ground began to cave in, so did the buildings.. A hotel swayed drunkenly and collapsed, its foundations torn away. For hundreds of guests it had been their holiday home; now it was their tomb.. Everywhere in the city, the story was being repeated with the continuous thud of falling masonry, the splintering of glass and the blinding clouds of dust.. Homes were smashed. Walls collapsed, ceilings fell in, bricks and beams fell. Wide fissures appeared in the streets.. As soon as the outside world heard of the earthquake, help began to pour in. Firemen, doctors, nurses and rescuers raced to Skopje. Hospitals made ...

MEDIA RELEASE. Medical teams from Hawaii are back from assisting federal medical relief efforts in the wake of Superstorm Sandy. Hawaii Disaster Medical Assistance Team (Hawaii DMAT) members combined forces with members of Alaskas DMAT to form three task forces, and joined with DMAT and national guard members from around the country. Their two-week deployment lasted through Thanksgiving.. Task Force 1, led by HAH Emergency Services Director Toby Clairmont, established a medical surge treatment area adjacent to the hospital Emergency department at South Nassau Communities Hospital. Team members provided care in the emergency department and in a field treatment facility located in the parking lot. The 200-bed Level II trauma center is in the disaster area very near heavily damaged areas of Long Beach, Coney Island and Rockaways. Many of the hospitals 3,000 staff lost their homes in the storm.. Amy Baker, PharmD, the Adverse Drug Event Project Lead at Mountain Pacific Quality Health, was one of ...
Results For the 46 patients, the female to male ratio was 1.3:1 and the mean age was 36.7 years. Most patients (41, 89.1%) were Tibetan. The most frequent cause of maxillofacial injury was pressing/burying (34 patients, 73.9%). All patients with maxillofacial injuries sustained soft-tissue injuries, 13.0% had facial fractures and 4.3% had dentoalveolar injuries. The soft-tissue injuries were largely combined injuries; 84.8% were bruises and 80.4% were lacerations. The most common injury site was the zygomatic region (54.3%), followed by the forehead (43.5%) and the orbital region (34.8%). Of the six facial fractures, four involved nasal-orbital-ethmoidal region fractures. Most of the maxillofacial injuries (78.3%) were associated with other injuries, of which extremity injuries (55.6%) were the most common. ...
Abraham Lincoln once said, Give me six hours to chop down a tree and I will spend the first four sharpening the axe.6 Are we prepared? Its not a question of if an emergency will occur but when and how bad. The events of September 11, 2001; hurricanes Katrina, Gustaf, and Ike; and the earthquake in Haiti underscore the urgent need for federal, state, regional, and public health care agencies to respond in unison and to respond effectively to such emergencies.7 As a first responder with the Disaster Medical Assistance Team CA-6, I concern myself with the immediate casualties in the impacted area and in our mobile receiving center, as well as in the primary receiving medical center. The mission is to stabilize and transport the patients to the appropriate medical facility having the best chance of saving them. That being said, resuscitation is really a matter of whatever it takes to save lives. In an event where multiple casualties are present, bystanders may, in fact, be the first responders ...
After the large-scale earthquake in 2011, the disaster medical assistance team (DMAT) was made responsible for medical activities during the hyperacute phase of a disaster or accident in Japan. The medicines to be administered at the disaster sites, packaged in medical bags, may be affected by the temperatures there. This study aimed at establishing a method to handle drug bags in high-temperature situations by determining the temperature changes in medical bags subject to high temperatures and examining the effect of opening the bag and using heat-insulating material (HIM) and coolants. Closed and semi-opened bags limited the temperature increase in the central part of the bag at both 35 and 40 °C to a greater extent than opened bags. When coolant and HIM were used in closed and semi-opened bags, the internal temperatures were significantly lower than in the opened state at 40 °C. In high-temperature disaster sites, medical bags should be maintained in a semi-opened or closed state using a HIM and

He is currently out with an abdomen injury, though should be back soon.
Tsunami vertical evacuation (TVE) buildings have the potential to save many lives. Yet whether TVE buildings actually save lives depends critically on whether people trust and evacuate to them, a question that has not previously been researched. We examine the case of the city of Banda Aceh, Indonesia, where a M8.6 earthquake on 11-April-2012 caused a spontaneous mass evacuation but no tsunami. Our survey of residents living near TVE buildings (n = 202) shows that they clearly prefer horizontal evacuation: in the 2012 earthquake, only 26% evacuated to a TVE building, while 74% evacuated horizontally; if a similar earthquake happened in the future, only 32% intend to evacuate to a TVE building, while 68% intend to evacuate horizontally. To investigate the reasons for this, we extend protection motivation theory to examine peoples choices among protective actions under social influence. Those who prefer to evacuate horizontally do not trust the safety of the TVE building and think they can reach ...
How many tourists visited Cuba in 2016?. The number of Cubans visiting Cuba increased significantly last year from the previous year.. According to Cubas National Tourism Organization (ENCA), in the first half of this year, Cuba saw an average of 1,812 tourists visiting the island, a figure that is now on track to surpass last years mark.. In 2016, there were 1,932 tourists visiting Cuba, a rate of almost 8,000 tourists per month, the ENCA said in its latest annual report.. Tourism to Cuba is not a priority for the Cuban government as it focuses on economic development and tourism.. The island has only one official airline, the National Aeronautics and Space Administration (NASA), which flies between Havana and the United States and Europe.. There are no official flights to the US, however, nor to Russia or Canada.. Cuba has not had a single major earthquake since 1959, although it has suffered at least eight earthquakes since 2009.. Most of the major earthquakes are related to natural ...
Natural disasters (earthquakes, volcanic eruptions, hurricanes, floods) affect the lives of hundreds of millions of people every year, and their impact is increasing year on year because of continuing expansion of human populations into increasingly exposed areas, with environmental degradation making these settlements more vulnerable, especially in heavily urbanized areas. Future climate change may exacerbate matters, with many forecasts predicting an increase in hurricanes, severe wind storms, flooding and droughts....
Twenty-nine young survivors of the deadly earthquake in Chinas Sichuan Province were in Taiwan for a holiday to help them recover from the trauma of the May 12 quake which killed 70,000 people, reports said Saturday, dpa reported.. The children, aged between seven years and their teens, were guests of the Chinatrust Charity Foundation, a Taiwanese charity.. Having visited Taipei, the capital of Taiwan, and the Taipei Zoo, the group on Saturday arrived in Nantou County in central Taiwan, to visit the site of the September 21, 1999 earthquake which killed 2,321 people and injuring 8,000.. They also played in an amusement park in Nantou County and attended the step over the fire ceremony, held by aborigines, to ward off bad luck. ...
MEXICO CITY, Sept. 21 - At least 216 people have been killed after a powerful earthquake hit central Mexico on Tuesday, with the death toll expected to rise due to the scale of the temblor, the countrys civil protection agency said.. The magnitude-7.1 quake toppled dozens of buildings, broke gas mains and sparked fires, sending thousands of people fleeing into the streets in panic. Fatalities were reported in capital Mexico City, nearby Morelos and Puebla states, the State of Mexico, and the south-central state of Guerrero, according to the head of Mexicos national civil protection agency, Luis Felipe Puente.. In his latest update of the number of people killed as a result of the major quake, Puente said there were 86 confirmed deaths in the Mexico City, 71 in Morelos, 43 in Puebla, 12 in Edomex and three in Guerrero. The toll is expected to climb as many people remain trapped in the rubble of collapsed buildings.. Dozens of buildings tumbled or were severely damaged in densely populated parts ...
t is well established that earthquake faulting can create permeability along a fault zone in high competence rocks - by mismatch of the fault walls and by secondary fracture in a surrounding damage zone - and that this permeability is created repeatedly during successive earthquake cycles. Less well proven is that such permeability is transient, being episodically reduced by precipitation of cements in the fracture porosity. The textures of carbonate dilation breccias, formed at around 1.7 km depth on the Dent Fault zone (NW England), lend support to this economically important concept of transient fracture permeability. The key observation is that many breccias reflect only a single episode of brecciation and reseal. A generally applicable explanation of such single-phase breccias is that they were resealed in the interval between major earthquakes, that this reseal made the breccia stronger that the intact rock, and that subsequent brecciation in the same rock volume was inhibited. This ...

Wellington - Two goldfish have survived 134 days since a devastating earthquake hit New Zealand without any pet food or electricity to power their tank filter.. The goldfish, named Shaggy and Daphne after characters in the television show Scooby Doo, were in a 100-litre tank in the reception area at Quantum Chartered Accountants in Christchurch when the earthquake struck, killing 181 people.. It was only this month that Quantum workers were allowed back into the building and found the fish alive.. Curator Paul Clarkson at the Monterey Bay Aquarium in California says bacteria may have kept the water clean enough to sustain life and the fish may have eaten algae growing in the tank. ...
http://www.nytimes.com/2011/05/17/world/asia/17japan.html?_r=2&src=tptw&pagewanted=all. OMAEZAKI, Japan - The nuclear power plant, lawyers argued, could not withstand the kind of major earthquake that new seismic research now suggested was likely.. If such a quake struck, electrical power could fail, along with backup generators, crippling the cooling system, the lawyers predicted. The reactors would then suffer a meltdown and start spewing radiation into the air and sea. Tens of thousands in the area would be forced to flee.. Although the predictions sound eerily like the sequence of events at the Fukushima Daiichi plant following the March 11 earthquake and tsunami, the lawsuit was filed nearly a decade ago to shut down another plant, long considered the most dangerous in Japan - the Hamaoka station.. It was one of several quixotic legal battles waged - and lost - in a long attempt to improve nuclear safety and force Japans power companies, nuclear regulators, and courts to confront the ...

The Palmer Observatory, under the auspices of the Coast and Geodetic Survey, was established in Palmer, Alaska in 1967 as a direct result of the great Alaskan earthquake that occurred in Prince William Sound on March 27, 1964. This earthquake alerted State and Federal officials that a facility was necessary to provide timely and effective tsunami warnings and earthquake information to the coastal areas of Alaska. Congress provided funds in 1965 to construct two new observatories and establish a tsunami warning system in Alaska. The first observatory constructed was at the U.S. Naval Station on Adak Island in the Andreanof Islands in the Central Aleutians. The City of Palmer, in the Matanuska Valley 42 miles northeast of Anchorage, was selected as the site for the primary observatory due to its proximity to bedrock for instrumentation and to communications facilities. Construction of the observatory installations, the task of engineering and assembling the data systems, and the hookup of the ...

Right away you can see differences in quake distribution between the top 10 quake regions. Some areas, like Southern Alaska and the Virgin Islands, had a pretty steady series of quakes, while the Fox Islands and Vanuatu experienced their seismic activity all at one point. You can easily get the minimum and maximum count for a particular region by mousing over the sparkline; in this example you can see that in Southern Alaska, the minimum count of quakes experienced in a single day during the 7-day period was 1, while the maximum count per day was 6. But what if you want your sparkline to represent not only the earthquake count, but also the relative average magnitude of the quakes affecting each region? In other words, how can you make the sparkline line chart represent average quake magnitude for each time bucket (segment) of the chart? Try a search like this: ...

Temporary Protected Status. The Department of Homeland Security (DHS) Secretary, Janet Napolitano, has determined that an 18-month designation of Temporary Protected Status (TPS) for Haiti is warranted because of the devastating earthquake and aftershocks which occurred on January 12, 2010. TPS beneficiaries are allowed to remain in the United States, and can legally work for a set time period. U.S. Citizenship and Immigration Services (USCIS) will efficiently and timely process immigration applications for TPS filed by nationals of Haiti.

As discussions on this issue continue, one thing seems clear: dispensing information during an emergency is important, but broadcasting alone doesnt maximize the potential of these social tools. To best help the public, experts insist that emergency organizations create two-way communications by also listening to the online chatter.. That became apparent during the 2010 Haiti earthquake, the first major disaster occurring in the Social Media Age. Born only a few years earlier, Twitter allowed disaster victims to supply an unprecedented level of information on what was happening on the ground. A lot of organizations and relief agencies would say that Haiti was when social media use during disasters really took off, but after the earthquake we noticed a critical piece missing in the way we use social media during those events, says Gloria Huang, senior officer of Humanitarian Social Engagement for the Red Cross. We were very good at putting content up [ourselves] … but we didnt have a way ...
Weeks after a giant tsunami engulfed Japans Fukushima nuclear plant, Tokyo Electric Power Co. is still struggling to bring the radiation crisis under control. Radiation has seeped into the soil and seawater and made its way into produce, raw milk and tap water. The Japanese government has admitted that its safeguards were insufficient to protect the nuclear plant. Radiation levels have increased in 15 US states from the nuclear disaster in Japan.
My research focuses on the analysis of seismic long-period (LP) events on various volcanoes. Whereas volcano-tectonic earthquakes on volcanoes are related to brittle failure of rocks (just like earthquakes), the sources of LP seismicity are still not fully understood. Source processes with fluids and resonance are the most widely accepted models for these sources today. However, due to the difficult volcanic environments, very few studies include data from summit-near stations. The Seismology Lab group at UCD has installed several temporary high-density networks in the summit areas of active volcanoes in the past (e.g. Mt Etna, Italy and Turrialba, Costa Rica). The data from stations in the near-field of LP sources (i.e. , 1 ¿ 2 km) show different behaviour than we would expect from a ¿classical¿ LP source.. I am working on the integration of broadband data from near-field stations into seismic source inversion. Their special behaviour (more impulsive waveforms, quasi-static displacements, ...
cases of accidental hypothermia. The types of emergency vary according to the kind of disaster and how and when it strikes. In earthquakes there is a high level of mortality as a result of people being crushed by falling objects. The risk is greatest inside or near dwellings but is very small in the open. Consequently earthquakes at night are more deadly. There are large numbers of injuries. During the night fractures of the pelvis, thorax and spine are common because the earthquake strikes while people are lying in bed. In the daytime injuries to the arms and legs, the collarbone and the skull frequently occur. There may be people in a state of shock and people suffering from bums (particularly in areas where electricity and gas are installed). Afterwards there may be surgical complications of fractures or infections of wounds. In volcanic eruptions mortality is high in the case of mudslides (23 000 deaths in Colombia in 1985) and glowing clouds (30 000 deaths at Saint-Pierre in Martinique). ...
From earthquakes to volcanoes to floods, the physical processes of the Earth have always affected people.. Geoscientists study the physical, chemical, and biological processes of the Earth, from its deep interior to its surface. Most people think that geology is just about rocks or oil and gas. However geoscience majors also study topics such as rivers, beaches, volcanoes, glaciers, earthquakes, plate tectonics, groundwater, global climate change, soils and sediments.. Using a wide variety of tools and techniques, students learn how geoscientists investigate environmental hazards (such as earthquakes, landslides, floods, hurricanes, beach erosion, volcanic eruptions, water pollution, and toxic chemical spills); the availability of mineral, energy, and water resources; and the history of the earth and its inhabitants.. The Geoscience program at Tarleton State University offers one degree with size concentration areas. All under the larger heading of Geoscience, these concentrations ...
Recent developments in earthquake engineering indicate that probabilistic seismic risk analysis (PSRA) is becoming increasingly useful for the evaluation of structural per-formance in accordance with building codes. In recent years, the field of seismic resis-tance design has been undergoing a critical shift in focus from strength to performance. However, current earthquake resistant design procedures do not relate building performance to probability. A lack of sufficient empirical data has highlighted gaps in this research. This study integrated results from the analysis of structural fragility and seismic hazard in Taiwan to perform PSRA to examine the effectiveness of building code in mitigating the risks associated with earthquakes. Factors taken into account included the effect of construction materials, building height, and building age. The results of this study show that the probability of exceeding damage associated with the CP level in buildings of light steel, pre-cast concrete, and masonry,
