Supervolcano

A revised and updated comprehensive examination of the supervolcanic eruption of Toba in Sumatra, Indonesia over 75,000 years ago, and how it changed human genetic history by causing a population bottleneck, written by best-selling author Marie D. Jones and her father, the late geophysicist Dr. John M. Savino, Ph.D. The book describes what a supervolcano is, how they form, where they are located across the globe, and which ones may be ready to erupt. Will Yellowstone be next? Features a fictional scenario of an actual eruption at the Long Valley Caldera in California, and what happens in the days, weeks and months to follow. Are we prepared for the apocalyptic devastation known as a supervolcano?
