VOLCANO LIGHTNING PHOTOS: Alaska's Redoubt Goes Electric
<< Previous   2 of 4   Next >>
In late March 2009 amateur photographer Bretwood Higman captured images of Alaska's Redoubt Volcano--80 miles (130 kilometers) north of his home--erupting, with fingers of lightning clutching the ash cloud.

Scientists also monitored the volcanic lightning with arrays of radio-frequency monitors spread out over hundreds of square miles to "map" one of the Earth's most spectacular natural light shows.
