00:00Something strange is happening under Yellowstone.
00:02And scientists just uncovered a chilling clue.
00:05Using machine learning, researchers found over 86,000 hidden earthquakes under Yellowstone from 2008 to 2022.
00:13That's 10 times more than we previously knew about.
00:16Even more alarming?
00:18Over half of them came in swarms, clusters of tiny quakes that often signal volcanic activity.
00:23These chaotic swarms were creeping along deep, jagged fault lines beneath the Yellowstone caldera,
00:29one of the most dangerous supervolcanoes on Earth.
00:32Experts believe these swarms are caused by hot, pressurized water and gas forcing their way through underground cracks.
00:39If Yellowstone ever erupted, it could cover two-thirds of the U.S. in ash, ground flights, poison the air, and force millions to flee their homes.
00:48But here's the twist.
00:50Scientists say this isn't a sign of an eruption just yet.
00:52Instead, these swarms are likely steam-driven, like the violent explosion last summer that blasted rocks sky-high at Biscuit Basin.
01:01Still, this discovery is massive.
01:03It could help scientists better predict volcanic risks around the world.
01:07Yellowstone may not be about to blow, but now we're finally learning to hear its volcanic heartbeat.
