  • About one-third (32%) of lightning injuries occur indoors. (
  • This will reduce the number of injuries if lightning strikes the ground. (

  • From 1987 through 2016, an average of 47 people lose their lives in the U.S. due to lightning, according to the National Weather Service. (
  • The majority (89%) of lightning deaths occur among whites. (
  • Most of the deaths occur immediately. (
  • Lightning strikes often occur in the afternoon. (
  • The theory behind this is during a lightning event a surge voltage is induced and as it moves through your house you want EVERYTHING to go up to a bazillion volts together. (
  • They can be as much as ten times stronger than other lightning strikes, or one billion volts. (
  • Most rainfall occurs in the northeast, in the Humid Pampa , Mesopotamia, and the eastern Chaco . (
  • Other lightning strikes sparked structural fires yesterday afternoon and evening. (
  • Fires started by lightning commonly occur during the dry season. (
  • Prior to European settlement, most fires within the park occurred as a result of lightning. (
  • Within this natural fire regime, low intensity surface fires typically occurred every 10 to 40 years in white and red pine forests. (
  • Severe stand replacing fires occurred in jack pine and upland black spruce forests every 50 to 75 years. (
  • Severe fires also occurred in spruce/fir/aspen forests every 70 to 110 years and in white and red pine forests every 150 to 250 years. (
  • In this article, we will look at lightning from the inside out so that you can understand this phenomenon. (
  • In his Dream Pool Essays of 1088 C.E. , the Song Dynasty polymath Chinese scientist Shen Kuo (1031-1095) wrote of the natural phenomenon of lightning. (
  • At the moment the eruption started, there were these sparks of lightning coming from the vent of Redoubt that only lasted 1 to 2 milliseconds. (
  • Benjamin Franklin (1706-1790) endeavored to test the theory that sparks shared some similarity with lightning using a spire which was being erected in Philadelphia . (
  • Lightning results from the buildup and discharge of electrical energy between positive and negatively charged areas. (
  • Diffusion typically occurs as isolated "rare" hops of atoms into vacancies (crystal defects). (
  • Stephen McNutt, a volcano seismologist at the University of Alaska Fairbanks's Geophysical Institute, became interested in lightning during the 1992 Mt. Spurr eruption. (
  • What causes lightning when volcanoes erupt? (
  • You often see spectacular photographs of lightning when volcanoes erupt. (
  • Chemical digestion of all nutrients mainly occurs in which organ? (
  • The late, eminent evolutionist, Robert Jastrow, founding director of NASA's Goddard Institute for Space Studies, said, " either life was created on the earth by the will of a being outside the grasp of scientific understanding, or it evolved on our planet spontaneously, through chemical reactions occurring in nonliving matter lying on the surface of the planet" (1977, pp. 62-63, emp. (
  • What this research means for the future of volcanology and meteorology is not yet clear but there is one thing that everyone, scientists and residents alike, agree on: The Mt. Redoubt eruption was "the most spectacular lightning display that they have ever seen. (
  • And now scientists have figured out just how quickly evolution was occurring during evolution's "big bang. (
  • Now, scientists from the US Air Force Academy say they have some new insights into reproducing the rare form of lightning in the laboratory. (
  • The lightning observed during the eruption of Mt. Redoubt in 2009, researchers have determined , is an entirely new variety. (
  • To measure the lightning, researchers deployed four Lightning Mapping Arrays prior to the eruption. (
  • In a collaborative study appearing in Nature , researchers from Japan describe how gamma rays from lightning react with the air to produce radioisotopes and even positrons - the antimatter equivalent of electrons. (
  • The reason you are safe in a car is because the lightning will travel around the surface of the vehicle and then go to ground. (
  • If lightning hits your vehicle, it will travel around the body of the vehicle and move toward the ground, he said. (
  • The brilliant white-blue flash of lightning is caused by its extreme heat. (
  • The current amount of nitrogen fixation that occurs by industrial processes equals that of natural, terrestrial nitrogen fixation. (
  • lightning, spontaneous combustion, hot ashes and arson. (
  • The first assumption is that non-living things gave rise to living material, i.e., spontaneous generation occurred" (p. 6). (
  • That's when you get lightning," she explains. (
  • After three people were shocked by positive lightning while working a crime scene in Round Rock, KVUE explains how. (
  • We already knew that thunderclouds and lightning emit gamma rays, and hypothesized that they would react in some way with the nuclei of environmental elements in the atmosphere," explains Teruaki Enoto from Kyoto University, who leads the project. (
  • Many factors affect the frequency, distribution, strength and physical properties of a typical lightning flash in a particular region of the world. (
  • Behnke explained that the arrays are "basically an old TV antenna set to pick up channel 3- the same frequency that lightning radiates from. (
  • We can't hear it without special equipment, but the planet almost continually sings with the sound of low-frequency radio signals that derive from lightning strikes. (
  • Some people have theorised that larger particles might have positive charges and smaller particles might have more negative charges and as larger particles fall out of the atmosphere faster, that might create the separation needed to generate lightning. (
  • The second afterglow, for example, was caused by lightning reacting with nitrogen in the atmosphere. (
  • When it passes through closed windows, the lightning ball damages them with small holes about one third of the time. (
  • Lightning can travel through any metal wires or bars in concrete walls or flooring. (
  • Lightning is one of nature's most common spectacles. (
  • Because human beings are terrestrial and most of their possessions are on the Earth where lightning can damage or destroy them, CG lightning is the most studied and best understood of the three types, even though IC and CC are more common types of lightning. (
  • Construction and material handling such as loading and unloading are two of the most common work-related activities where lightning strikes occur. (
  • The more traveling your fruit and vegetables have to do before you buy them, the more greenhouse emissions they contribute to the Plus, lightning strikes are more common when it's hot outside. (
  • Windstorms ( pamperos ) with thunder, lightning, and hail are common. (
  • Asthma, sickle cell trait, blood clots, cervical spine fractures, infection and lightning all caused more football deaths over those 20 years. (
  • empiric risk the probability that a trait will occur or recur in a family based solely on experience rather than on knowledge of the causative mechanism. (
  • genetic risk the probability that a trait will occur or recur in a family, based on knowledge of its genetic pattern of transmission. (
  • Lightning creates light in the form of black body radiation from the very hot plasma created by the electron flow, and sound in the form of thunder . (
  • A typical lightning discharge may consist of several hundred to a few thousand located sources. (
  • Ammonia is a naturally-occurring compound that is an intermediate in the global nitrogen cycle. (
