Mt. Toba in the island of Sumatra exploded a short while back, in geological terms just 71,000 years ago and all but exterminated humanity leaving only some 6,000 human beings alive on planet Earth. The energy source for this rambunctious region is still active. It killed some 250,000 people from an earthquake and associated tsunami on December 26, 2004. Humans are now spread all over the planet and most are much further away from that single source of destruction so it is unlikely that it, or any other earthquake will destroy the whole species at this time. But, there is a possibility that a super landslide into the ocean from the Canary Island of La Palma forming a megatsunami could kill millions in the eastern side of North and South America. The tsunami from a land slide at Lake Tahoe would throw some water on my summer vacation but it wouldn’t be an existential risk for humanity. My September residence near the top circle of four circles at the bottom is still deep under water even after the water has run back from the mountain sides. See some moving simulations.
These megadisasters are natural but they will not destroy humanity.
