The Dirty Thunderstorm
A dirty thunderstorm, also “Volcanic lightning” is a weather phenomenon that occurs when lightning is produced in a volcanic plume. A study indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms. Volcanic eruptions also release large amounts of water, which may help fuel these thunderstorms.
