Overview

Approximately 75,000 years ago, an event occurred that almost wiped out human life. According to a stunning new theory, this singular event may also have completely altered the genetic evolution of humankind. It was an event that released 3,000 times the energy of Mount St. Helens. That event was the eruption of the Toba supervolcano in Sumatra, Indonesia-the largest volcanic eruption in two million years. So devastating was the eruption and the sheer amount of ash it released into the atmosphere, it altered the global climate for years, creating a mini Ice Age that obliterated massive amounts of plant, animal, and human life. Now a fascinating theory called the "Toba Catastrophe Theory" claims this earth-shattering event also caused a severe "population bottleneck" in humans, leading to the eventual extinction of all other branches of our species with the exception of one...the branch that survived Toba and became modern humans.

The book Supervolcano will explore: What supervolcanos are, where they are found, and why they are so deadly to life on Earth. How genetic, geological, and computer studies show that each human today is related to a survivor of Toba. How we can prepare for the next supervolcano, which could be right here in our own backyard-Yellowstone National Park or Long Valley, California-and why an eruption at either location could be as catastrophic for humanity as Toba.
