Our new @bullvolc paper is finally out on #VolcanicLightning during the submarine eruption of Bogoslof volcano in the Alaskan Aleutians! You can read the full study here--> rdcu.be/b1j0m. But here's what you need to know... [credit to @alaska_avo site for photos] (1/10) From the surface, Bogoslof looks like any other wind-swept island, much beloved by seals, sea lions, and #puffins in the Bering Sea. It also happens to be an active volcano. The island is just the tip of the iceberg of a huge stratovolcano rising 6k ft from the ocean floor (2/10)

If you're mesmerized by the steamy #Taal eruption plume and wondering why it's creating so much #VolcanicLightning, you’re not alone. Here’s a micro-crash course on the physics of volcanic thunderstorms for non-specialists. Thanks to @joshibob_ for the incredible footage! (1/14) It starts with explosive fragmentation of hot rock under Lake Taal, which leads to vigorous magma-water interaction. This process vaporizes the lake water AND pulverizes the erupted rocks into even smaller particles known as volcanic ash. (2/14)
