Scientists get rare opportunity to monitor caldera collapse in real time

Many of the most catastrophic volcanic eruptions in history have something in common: caldera collapse — the formation of a large hole by the collapse of a volcano’s peak associated with the emptying of the magma chamber. But these events are rare. So, in August 2014, when Bárdarbunga Volcano in central Iceland erupted, it gave scientists the unique opportunity to study a caldera collapse in real time.
