Lightning cracks during an eruption
of Iceland’s Eyjafjallajökull volcano in 2010.
The eruption’s ash clouds delayed
European air travel for nearly a week.
Storms over volcanoes contain the
same ingredients as storms over your hometown—water droplets, ice, and
occasionally hail. The interaction of all of these elements creates an
electrical charge that sparks lightning. Active craters add ash to the mix.

Ash” and “Pictures: Volcano Lightning, Illuminated.”)
