While rare "lava lakes" like those at Mount Erebus do exist, the vast majority of Earth's volcanic activity—approximately 75 to 80 percent—occurs underwater along mid-ocean ridges. Volcanic phenomena also generate extreme weather; "dirty thunderstorms" occur when colliding ash and ice particles create massive…
