Gradual caldera collapse at Bárdarbunga volcano, Iceland, regulated by lateral magma outflow
Large volcanic eruptions on Earth commonly occur with a collapse of the roof of a crustal magma reservoir, forming a caldera. Only a few such collapses occur per century, and the lack of detailed observations has obscured insight into the mechanical interplay between collapse and eruption.We usemult...
