Super Volcanoes
Synopsis
A super volcanic eruption could kill millions and devastate the United States, with ash potentially blanketing half the country.
Synopsis
Geologist Bob Christensen investigates Yellowstone National Park, where unusual geological activity was reported in spring 2003. The tallest geyser, Old Faithful, erupted after a 50-year dormancy. Cracks appeared in the ground, and bison died from toxic fumes. Scientists warn that a super eruption could kill thousands and disrupt society. Continuous monitoring of Yellowstone is essential, as super volcanoes are rare but pose a significant threat. The last major eruption occurred 74,000 years ago, and the next could have catastrophic consequences.
