The February 2008 issue of Elements Magazine was taken to press on February 8 with a likely distribution of March 1st. Supervolcanoes (v.4 no.1 - February 2008)Guest Editors: David A. Wark (Rensselaer Polytechnic Institute and GE Global Research) and Calvin F. Miller (Vanderbilt University)Explosive super-eruptions from large-volume, shallow magma systems lead to enormous and devastating pyroclastic flows, the formation of gigantic collapse calderas, and deposition of volcanic ash over continent-sized areas. Recognition that future eruptions from these "supervolcanoes" will undoubtedly have severe impacts on society-and perhaps on life itself-has led to recent public and media interest. Should we be concerned about an imminent super-eruption? The answer to this question requires an understanding of past eruption events. In this issue, geoscientists investigating ancient supervolcanoes provide insight into the processes and the time required to generate large volumes of eruptible magma, the monitoring of a youthful system, and super-eruption processes and consequences.
