January 2014 Geology: Volcanic Lightning?

Posted on 10 Jan 2014 by Kea Giles
A volcanic plume generates an impressive lightning bolt at Sakurajima volcano, Japan. Self-electrification of ash particles and charge distribution within the plume are controlling factors for volcanic lightning generation. See “Experimental generation of volcanic lightning” by Cimarelli et al., Geology, Jan. 2014, p. 79–82. Photo by Martin Rietze.
