There are 20 supervolcanoes on Earth that represent that greatest natural threat to human life, writes ‘End Times’ author Bryan Walsh.
The Yellowstone supervolcano is an eight out of eight on the Volcanic Explosivity Index but has only erupted three times in the last 2.1 million years. The last eruption was 640,000 years ago.
Volcanologists predict an explosion could spread toxic gas all the way to the Midwest, ruining crops and knocking out power, according to Walsh. He adds that a toxic cloud blocking the sun could cause much colder temperatures in the United States for years.
The European Science Foundation said it would be ”the greatest catastrophe since the dawn of civilization,” according to Walsh.
He says that supervolcanoes represent an “ultra-catastrophe” that could lead to human extinction. Other examples are an asteroid, and nuclear or biological warfare. He suggests that although an eruption in our lifetime is unlikely, one could decimate the planet.
