Volcanic Eruption Produces Lightning

From LiveScience:
When Alaska’s Mount Redoubt volcano began rumbling back to life in January, a team of researchers scrambled to set up a system called a Lightning Mapping Array that would be able to peer through the dust and gas of any eruption that occurred to the lightning storm happening within. Lightning is known to flash in the tumultuous clouds belched out during volcanic eruptions.
The lightning produced when Redoubt finally erupted on March 22 was “prolific,” said physicist Paul Krehbiel of New Mexico Tech. Check out the image.
