"The mingling of lightning and ash seen above may be a "dirty thunderstorm."
The little-understood storms may be sparked when rock fragments, ash, and ice particles in the plume collide to produce static charges—just as ice particles collide to create charge in regular thunderstorms."
The volcano spewed ash and debris more than 12 miles high.
Here is a satellite photo showing how far the plume stretches. Areas beneath the plume were buried under as much as 6 inches of volcanic ash.
As impressive as that is, it ain't shit compared to the super volcano that lies beneath Yellowstone National Park, which could blow at any moment.
Have a nice day.
