The volcanic formation, which sits underneath the 30-by-45-mile Yellowstone Caldera, is among the most studied on Earth due to its potential for a supereruption when a volcano ejects over 230 cubic ...

Deep beneath Japan’s Kikai caldera, a massive magma reservoir is refilling 7,300 years after one of the most powerful ...

For decades, volcanologists have compared their craft to weather forecasting stuck in the 1950s: plenty of instruments, not nearly enough certainty. That gap is narrowing faster than most people ...

Retrospective and scenario-based analyses at five volcanoes show how warning thresholds can balance precautionary costs ...

Population models suggest the Kikai-Akahoya eruption brought severe regional decline alongside continued growth on some ...

Prehistoric communities on the Japanese island of Kyushu lived through one of the largest volcanic eruptions of the Holocene ...

Scientists have shed light on a thermal process in magma that may help explain why similar volcanic systems can produce very different eruptive behaviors. An international team, led by The University ...

Since early May, an undersea volcano has been erupting in the Bismarck Sea, along a feature that scientists call the Titan Ridge. It’s in the southwestern Pacific Ocean, just off the north coast of ...

Scientists say coarse ash lingered 20,000 feet up and 124 miles from source, requiring safety model updates ...

Seven thousand three hundred years ago, a volcano erupted from beneath the sea off the coast of southern Japan with a force that ranks among the largest of the entire Holocene. The eruption unleashed ...
