A supervolcano eruption could be catastrophic, but 'wouldn't wipe out humanity:' Doomsday Scenarios, ep. 3

A volcano erupted underwater in Tonga recently, starting a tsunami that caused incredible damage. The blast was visible from space. So how much damage could a massive eruption from a supervolcano actually do? Where are the hot spots? And what would happen one mile, ten miles, and a hundred miles away from the eruption? There's a little bit of good news -- Dr. Loÿc Vanderkluysen, associate professor in volcanology at Drexel University says although a supervolcano would have catastrophic effects, the odds are pretty good it would not entirely wipe out humanity.
