Volcanic Lightning
"It’s mostly associated with explosive volcanism, so the grey eruptions, like Shinmoedake in Japan, or the one in Iceland in 2010. The ones that actually generate this highly fragmented magma, volcanic ash, in the atmosphere."
While many news organisations report these events as simultaneous volcanic eruptions and electrical storms, Crozier says that’s actually not the case.
"A lot of people think it’s two extreme events, but the lightning strikes occur inside the eruption column itself and they’re actually caused by the charged ash particles that are being ejected into the column by the volcano."
