- Early Friday morning, officials said, several explosions erupted from the volcano, sending steam and ash into the air. (ktvu.com)
Plume3
- The scientists launched flights of small electric aircraft, equipped with cameras and sensors, into the volcanic plume of the Turrialba Volcano reported NASA. (qcostarica.com)
- On the morning of May 6, 2010, NASA's Terra satellite captured this view of a thick plume of ash (brownish-yellow) blowing east and then south from Iceland's Eyjafjallajokull volcano. (livescience.com)
- The ash-cloud image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite shows a thick plume of ash blowing east and then south from the Eyjafjallajökull volcano. (livescience.com)
Geologic1
- We performed the first rigorous statistical analysis of the distribution of volcanoes in the new global geologic map of Io," says Hamilton. (sciencedaily.com)
Closely2
- Officials also were closely monitoring Taal Volcano south of Manila and Mount Kanlaon on central Negros island due to renewed signs of restiveness. (ctvnews.ca)
- Since then, scientists have been monitoring the volcano more closely to avoid similar incidents. (madisonflowergarden.com)
Activity7
- Assuming that the volcanoes are located above where the most internal heating occurs, the team tested a range of interior models by comparing observed locations of volcanic activity to predicted tidal heating patterns. (sciencedaily.com)
- To continue the analogy, volcanologists have also found that, unfortunately, not all volcanoes are “keyed†alikeâ€"indicators of activity on one volcano do not always apply to another one. (hawaii247.com)
- Hiller says he was surprised to find that the density of small volcanoes dropped in the area around Iceland, as Iceland is known to be a hotspot for volcanic activity . (newscientist.com)
- If the ground around the volcano starts to bulge or shift, it could be a sign of impending volcanic activity. (madisonflowergarden.com)
- Firstly, it allows scientists to detect any changes in the activity of the volcano and provide early warning to the public. (madisonflowergarden.com)
- Q: How do scientists monitor volcanic activity? (madisonflowergarden.com)
- Although it is currently showing increased activity, thanks to the tireless work of scientists, the public can be quickly alerted to any incoming danger. (madisonflowergarden.com)
Researchers3
- One of the 13 mangled, mummified mice that researchers found on top of Andean volcanoes. (yahoo.com)
- The summit of Volcán Salín (19,780 feet above sea level), one of three volcano summits where researchers excavated mouse mummies. (yahoo.com)
- He says his findings may mean that researchers need to re-assess their understanding of how submarine volcanoes are formed . (newscientist.com)
Summit1
- When the Sonne returned to Monowai later in the three-week voyage, the scientists found part of the Monowai summit had collapsed and another part had grown substantially. (rdworldonline.com)
Solar System1
- The tubular cloud forms and fades daily for about 80 days or so of a Martian year - which lasts about 687 Earth days - stretching from the Arsia Mons volcano to Olympus Mons, which just happens to be the tallest mountain in the solar system. (zmescience.com)
Thousand1
- In Costa Rica, 3 Dragon Eye drones did 10 trips to the interior of the volcano creater that is 3 thousand and 340 meters high from the 11 to 14 of march. (qcostarica.com)
Search1
- Storz's team is also continuing to search the volcano tops for signs of mice, living or mummified. (yahoo.com)
Hawaii3
- One of them focuses on the fact that all three volcanoes lie within the rupture zone of the 1957 "Great Aleutian Earthquake," a magnitude 8.3 tremor that generated a tsunami that damaged buildings in far-off Hawaii. (sott.net)
- Another surprise was that he found fewer volcanoes on the seabed around Hawaii, another volcanic hotspot. (newscientist.com)
- Q: Is it safe to visit Hawaii now that the volcano is more active? (madisonflowergarden.com)
Cloud4
- Scientists affiliated with the European Space Agency (ESA) just released a stunning photo of the giant 1,100-mile-long (1,800 km) cloud captured by the Visual Monitoring Camera (VMC) on the Mars Express spacecraft. (zmescience.com)
- That being said, the volcanoes are indeed responsible for forming the elongated Martian cloud , but not in the way you likely imagine. (zmescience.com)
- Once all of this data was pooled together, it quickly emerged that the Martian cloud is "orographic" or a "lee" cloud, meaning it forms when the atmosphere is pushed upward by surface features such as mountains - or in this particular case, very tall volcanoes with a leeward slope facing downwind. (zmescience.com)
- Meanwhile, three airlines have cancelled flights out of Argentina's busiest airports Ezeiza and Aeroparque because of the ash cloud in the atmosphere from Chile's Puyehue volcano which erupted this past weekend. (ibtimes.com)
Discovery1
- The discovery has baffled scientists who did not think mammals could live at such high elevations . (yahoo.com)
Tall1
- The programme found 201,055 volcanoes over 100m tall. (newscientist.com)
Bubbles1
- They suspected a growth spurt was underway when they approached Monowai on the Sonne in May 2011 and observed discolored seawater and gas bubbles rising above the volcano. (rdworldonline.com)
