Scientists capture volcano’s lightning Electrical discharges mapped inside Mount Redoubt’s clouds of ash
By Andrea Thompson Senior writer
For the first time, scientists have been able to “see” and trace lightning inside a plume of ash spewing from an actively erupting volcano.
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.

"volcanic plumes spin like tornadic thunderstorms, a finding that helps to explain the lightning storms as well as the waterspouts and dust devils produced by some volcanic plumes."
Pretty amazing.

Years ago when the vents on Kilauea went off at Pu'u O'o, Pu‘u Halulu, Pu‘u Kahaualea, and Pu‘u Kamoamoa there were thunder and lightning storms that blacked out large areas in Puna. One storm knocked out the power grid for several days, lightning strikes on electric poles with condensers and even tall Alexandra palms throughout the area.
There maybe correlation with the acidic air borne particulate matter and ejecta that made the normally occurring storm worse but I've seen nothing on this from the USGS locally or the electric company assessment of the phenomena.
