#6. Super Volcano
This isn’t a normal type of volcano. In the USA, there is a super volcano, that you probably heard of ” Yellowstone”. There are other super volcanoes across the world, in places like Japan. Instead of lava reaching only a few miles, lava flows from a super volcano would reach hundreds of miles away. The pyroclastic clouds would engulf cities as far as Seattle and St. Louis. Even if areas within hundreds of miles would be destroyed, it doesn’t stop there. There would be global darkness for years. Weather systems would be interrupted, including the monsoon winds of the Indian Ocean, causing massive famines. The temperature would fall, and we would lose all of the Sun’s light. Every crop would just die, and we would starve to death. There would be ash in the air, choking all animals. The ash would ground planes, take down the electricity, and cause buildings thousands of miles away to collapse.
