Volcano Lightning

A new report revealed that volcanic lightning storms can be as powerful as giant Great Plains thunderstorms and that more lightning means a bigger plume of ash.

There are at least two types of volcanic lightning, a new radio-mapping study found. One occurs at the mouth of the volcano, and the other electrifies the heights of the plume, possibly as rising water becomes a mix of droplets and ice-coated ash particles.
