The caption says this volcanic 'light show' was caused from "an accumulation of static electricity". If that is so, I do not know the physical reason for that at all. Hopefully, someone can enlighten the ignorant. If it is something other than that, possibly, my guess would be that...

Well, that sounds spectacular and terrifying.

My understanding of why Mars lost its atmosphere was because it cooled down too much internally and that when this happened, the planet lost its magnetic field that helped protect it from solar winds (which then ended up stripping away the planets atmosphere). Is there anything that people could...

How deep can a submarine volcanic vent be and still generate a significant pumice raft ? Sadly, Wiki is a stub, and most of the relevant literature is pay-walled. As I understand it, deep vents may generate a lot of pumice, but it never reaches the surface, just stays on the vent's flanks...

I was at the Smithsonian last year. They had a wonderful exhibit on human evolution. One of the displays mentioned the Toba eruption 75,000 years ago and how after that we were left with 1,000 - 10,000 human breeding pairs. How is this estimate being made? Is there also some information...

Recently, there has been an argument of whether or not you would sink if you were unlucky enough to fall into a volcano. The proponents of this argument focus their attention on the water/magma density difference. Since the human body consists of 60-70% water, and water is less dense than...

The tallest volcano in the solar system is the 19 km tall Martian volcano, Olympus Mons. An astronaut drops a ball off the rim of the crater and that the free fall acceleration of the ball remains constant throughout the ball’s 19 km fall at a value of 4 m/s2. (We assume that the crater is...

A 500m high volcano eject rocks at a speed 30 m/s.What is max horizontal distance reached by the rock?

Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500km (or even higher) above the surface. Io has a mass of 8.94×10^22 [kg] and a radius of 1815km . Ignore any variation in gravity over the 500km range of...

Take Yellowstone for example, we do not know when it will erupt again, but we know sometime in the future that it will. We theorize that its driven from a stationary hotspot system which remains stationary as the Earth's upper crust continually slides over it until a weak spot or a spot of the...
