Lightning commonly occurs in the eruption columns produced by explosive volcanic eruptions. There are several different kinds of lightning detection instruments that could be employed to help monitor volcanoes, each with their own advantages and disadvantages. Very low frequency (VLF) instruments have ...
Ninety-one percent of the lightning during the event was observed by only one of the lightning sensors, thus showing the importance of combining lightning datasets across multiple frequencies to characterize electrical activity in volcanic eruptions. GLM flashes during the event had a median total ...
Is lightning always produced by a thunderstorm? Thunderstorms always have lightning (thunder is caused by lightning, and you can’t have a thunderstorm without thunder), but you can have lightning without a thunderstorm. Lightning can also be seen in volcanic eruptions, extremely intense forest fire...
The enormous eruption generated hundreds of times more power than an atomic bomb—and the most extreme lightning ever recorded. How did it happen?
more or less, it looks like the fragmentation of magma during an explosive eruption causes the ash to gain a charge! however, this would only apply to lightning near the volcano, so why is there lightning far downwind? that might be caused by the same mechanisms that generate lightning in ...
Using lightning observations as a volcanic eruption monitoring tool During the 2009 eruption of Redoubt Volcano, Alaska, USA, each of these types of instruments detected lightning from Redoubt's ash plume. The VHF system... SA Behnke,SR Mcnutt - 《Bulletin of Volcanology》 被引量: 19发表: 20...
Corrado Cimarelli of Ludwig Maximilian University in Munich, Germany, and his colleagues simulated a volcanic eruption by placing ash in a shock tube — an instrument that generates blasts. Drastically decompressing the ash caused it to explode upwards into a tank. Credit: CORRADO CIMARELLI/MIGUEL...
Destruction and Recovery of Vegetation Caused by the 2000-Year Eruption on Miyake-Jima Island, Japan The active Mt. Oyama volcano on Miyake-jima Island in the Izu Islands, Japan, erupted in 2000 followed by large amounts of volcanic gas containing high concentrations of SOhas been emitted. The...
For example, scientists have found that lightning occurs in the atmospheres of other planets, like the gas giant Jupiter (appropriately!) and the hellish world of Venus. And according to arecent studyfrom Kyoto University, gamma rays caused by lighting interact with air molecules, regularly produci...
s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: The global warming over the last half-century has been caused mainly by human ...
