Kim Genareau’s volcano lightning research in the news

Dr. Kim Genareau’s recent paper in Geology¬†is highlighted in several news articles such as, Science, ¬†Science News, KQED,¬†and Science Daily. Her research describes how extreme heating¬†of airborne ash by lightning can create tiny glass spheres as seen below. ¬†Such spheres were documented in deposits from¬†the recent eruption’s of Mount Redoubt in Alaska and Eyjafjallaj√∂kull in Iceland. ¬†This discovery provides a way to detect ancient volcanic lightning and indicates changes to the properties of ash movement. ¬†This paper is especially timely considering the recent eruption in Chile with spectacular lightning.
