Scientists in the United States have 'blown the lid off' the Yellowstone supervolcano's mysterious underground reservoir of magma. A team of geologists and Earth scientists now claims to have finally ...

Yellowstone National Park sits atop one of Earth’s largest volcanic systems, and right now that system is slowly reshaping the ground. Instruments show that the Yellowstone caldera is inflating into a ...

Shortly before 10 a.m. on July 23, 2024, a violent hydrothermal blast ripped through Biscuit Basin in Yellowstone, hurling mud and steam into a towering plume estimated at 400 to 600 feet high. The ...

Videos of animals appearing to flee Yellowstone National Park have gone viral, leading to speculation that the park’s infamous “supervolcano” may be about to blow. Climate website Green Matters ...

A caldera—like the one at Yellowstone Park spanning parts of Wyoming, Idaho and Montana—is a large depression or hollow formed when a volcano erupts and the magma chamber beneath it empties, leading ...

A sideways flow of hot mantle rock, not a deep plume rising from near Earth's core, may be feeding one of the planet's most closely watched supervolcanoes. That is the picture emerging from a new ...

A gigantic bulge in the north rim of the Yellowstone caldera is the latest sign of volcanic activity in the national park. Geologists call this type of bulge “volcanic uplift.” It’s often caused by ...

The magma reservoir of the largest volcanic eruption of the Holocene is refilling. This Kobe University insight on the Kikai caldera in Japan allows us to understand giant caldera volcanoes like ...

The Grand Prismatic hot spring in Yellowstone National Park is sourced from a magma chamber beneath it. The bright colours are produced by hydrophilic bacteria in the mineral-rich water. Yellowstone, ...

We know very little about the processes that lead to a reeruption of supervolcanoes such as the mostly underwater Kikai caldera in Japan (pictured) and are therefore ill-equipped to make predictions.
