Jan 1, 2025 · Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there's no need to worry at the moment.

Jan 9, 2025 · They found four pockets together contain more liquid magma than was present during large, caldera-forming eruptions at Yellowstone in the past (one 2.8 million years ago, one 1.3 million years ago ...

Jan 21, 2023 · Yellowstone's supervolcano last erupted 70,000 years ago. Will it erupt again anytime soon?

Feb 1, 2025 · The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in …

Feb 1, 2025 · Yellowstone’s history of massive eruptions. Researchers have long noted three massive eruptions in Yellowstone over roughly two million years. Those events left behind giant calderas, which are vast volcanic depressions formed when large volumes of magma empty and cause the ground to collapse.

Yellowstone is not overdue for an eruption. Volcanoes do not work in predictable ways and their eruptions do not follow predictable schedules. Even so, the math doesn’t work out for the volcano to be “overdue” for an eruption. In terms of large explosions, Yellowstone has experienced three at 2.08, 1.3, and 0.631 million years ago.

Jan 2, 2025 · The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey – the highest rung on the scale.To compare, Mt. …

Jan 27, 2025 · Over the past two million years, the volcano significantly erupted three times, leaving behind calderas, or massive craters. To better understand future eruptions, Ninfa Bennington, a volcanic seismologist with the U.S. Geological Survey, used magnetotelluric methods to identify four pots of magma stored underneath the Yellowstone Caldera.

Nov 7, 2023 · Three extraordinarily large explosive eruptions in the past 2.1 million years each created a giant caldera within or west of Yellowstone National Park. During these eruptions, enormous volumes of hot, fragmented volcanic rocks spread outward as pyroclastic density currents over vast areas.

Jan 6, 2025 · A new analysis published last week in the journal Nature suggests Yellowstone is unlikely to experience another big eruption—at least, not anytime soon—because the magma lurking beneath its ...
