00:00A major new geological discovery has revealed that Yellowstone Supervolcano's underground system
00:05is even larger and more complex than scientists previously understood.
00:10And critically, parts of it show signs of active movement.
00:14Researchers using advanced seismic imaging have mapped a previously unknown secondary magma pathway
00:20running beneath the western edge of the Yellowstone caldera in Wyoming.
00:25This pathway connects to the main magma reservoir at unexpected depths.
00:30Suggesting the system can distribute heat and pressure across a wider area than earlier models showed.
00:35Scientists are careful to say this does not increase the likelihood of a near-term eruption.
00:41Yellowstone's last full eruption was over 640,000 years ago.
00:46But the discovery does reshape how emergency planners model the potential impact zone.
00:51A full Yellowstone eruption would blanket large portions of the United States in volcanic ash,
00:57with some models showing meaningful ash fallen states as far away as Texas and the East Coast.
01:02A full Yellowstone eruption is not long-term eruption.
01:02It is now going out of an impact zone.
01:03Let's just say the reserve of the È-N-RA.
01:03We are going out of the middle of the A-N-R.
01:03We are going out of the A-N-RA.
