We Have A Supervolcano Problem

We have a potential supervolcano problem on our hands, although it does not involve the Yellowstone volcano or Italy's Campi Flegrei volcano (which is sometimes called a supervolcano by some people). Rather, the problem relates to a wider group of volcanoes that are sometimes called supervolcanoes, such as the Aira Caldera in Japan and the Valles Caldera in New Mexico. As, some scientists cannot seem to pin down exactly what they mean when they state the word "supervolcano", which has resulted in a seemingly ever broader definition for the term.

This image was then overlaid by text, and then overlaid with GeologyHub made graphics (the image border and the GeologyHub logo). Note: This video's thumbnail image displays Alaska's Okmok volcano erupting on August 2nd, 2008. The Okmok volcano is not classified as a supervolcano. Note: For this video, an “active” supervolcano means a volcano which has produced an either greater than 300 cubic kilometers or greater than 1,000 cubic kilometers eruption (depending on the definition used) at some point in the last 2 million years. This means that these volcanoes may not have erupted for over a million years.
