The volcano creates its own lightening.

Lightning crackles around a miles-high ash plume above Chile's Puyehue volcano (map) on Saturday.

A volcanic lightning storm isn't "unlike a regular old thunderstorm," Martin Uman, a lightning expert at the University of Florida in Gainesville, told National Geographic News in 2010.

The same ingredients are present: water droplets, ice, and possibly hail—all interacting with each other and with particles, in this case ash from the eruptions, to cause electrical charging, Uman said. (See pictures of a volcanic lightning storm in Iceland.)
