Figure 1: A map of structural, thermal and volcanic features in and around Yellowstone caldera. Past episodes of uplift and subsidence in the caldera have been attributed to various combinations ...

Yellowstone volcano: Caldera MAP shows USA covered in volcanic ASH after ERUPTION A YELLOWSTONE volcano eruption could be the most catastrophic natural disaster to strike the modern world ...

The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .

Henry Wood Elliott was a dedicated conservationist and explorer who, in 1871, helped create the first bathymetric map of Yellowstone Lake. Unlike many of his contemporaries, however, he declined to ...

Volcanic activity bubbling away beneath the Yellowstone National Park in the US appears to be on the move. New research shows that the reservoirs of magma that fuel the supervolcano's wild ...

New research has revealed when Yellowstone's supervolcano will erupt next, as it now contains a higher volume of magma than ...

This is equivalent to the volume of magma released roughly 1.3 million years ago during the Mesa Falls eruption—the second most recent caldera-forming eruption at Yellowstone.

The area northeast of Yellowstone Lake is home to the three largest-known hydrothermal explosion craters on earth: Mary Bay, a mile-and-a-half wide crater formed 13,000 years ago; Turbid Lake, a ...

Inside Yellowstone's fiery heart: Researchers map volatile-rich cap, offering clues to future volcanic activity. ScienceDaily . Retrieved June 11, 2025 from www.sciencedaily.com / releases / 2025 ...

Meanwhile, the largest pool of near-surface molten rock is east of the caldera, which may ultimately drive a transition of explosive eruptions outside the present caldera. Nature, 2025. DOI: 10. ...

Scientists have worked out the consistency of the magma under the Yellowstone caldera using seismic waves — and the reservoir is filled with "mush" that doesn't pose an imminent eruption threat.
