Detecting Icing Events

The following press release was published by the U.S. Department of the Interior, National Park Service on Feb. 21. It is reproduced in full below.

Introduction

Calderas form when magma chambers are partially emptied during large eruptions and the land surface subsides and the area above the shallow magma reservoir collapses. Explosive calderas form during especially large Plinian and Ultra-Plinian eruptions that send ash columns high into the stratosphere and create large-volume pyroclastic flows.
