The Recent Megaeruption in Greece; The Kos Nisyros Volcano

Within Greece is a largely hidden volcano which was the site of one of the world's largest eruptions in the last 1 million years. Largely hidden from view, it encompasses sections of both the islands of Nisyros and Gyali. This megaeruption deposited more than 200 meters or 656 feet thick of pumice and ash in a single eruption. The pumice contained in this layer is now widely mined for use in concrete. So, how long ago did this eruption occur? Why is this apparent volcano no longer visible? This video will answer these two questions and discuss this caldera forming eruption.
