Few natural phenomena inspire as much fascination and concern as the Yellowstone supervolcano. Beneath the park’s famous ...

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.

Deep under the western United States, two of the planet’s largest volcanic systems are quietly reshaping rock and gas. In California and Wyoming, scientists have reported unusual behavior that has ...

Far beneath the ocean near Japan, scientists have discovered that the magma system linked to the most powerful eruption of the Holocene is slowly rebuilding. By using seismic imaging, researchers ...

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 ...

Spatiotemporal correlations between moderate-to-large earthquakes and volcanic eruptions indicate that earthquake-induced stress changes can trigger eruptions. Triggering is rarely instantaneous, with ...

Will Yellowstone erupt or are we blowing things out of proportion? We may have underestimated Yellowstone’s potential to blow its stack in the future. Chinese scientists have made a disconcerting find ...

Melt re-injection after a giant caldera eruption was quantitatively investigated for the Kikai Caldera Volcano in Japan, which erupted 7300 years ago (Kikai-Akahoya eruption). Our seismic refraction ...

Have you ever wanted to look straight into an active volcano? A new USGS helicopter video offers a breathtaking look into ...
