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.

Caldera volcanic eruptions create geological hazards that affect many communities around the world. Geophysical, geochemical and remote sensing data have become essential for understanding the tectono ...

Deep beneath Japan’s mostly submerged Kikai caldera, scientists have discovered a vast magma reservoir that appears to be filling again. The volcano produced the largest eruption of the Holocene 7,300 ...

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 Yellowstone Caldera is a volcanic caldera and super-volcano in Yellowstone National Park, located in the Western United States—it has sometimes been referred to as the Yellowstone Super-volcano ...

Aerial view of Crater Lake in Oregon, a collapse caldera formed by one of the largest volcanic eruptions in the past 8,000 years. A detailed survey of the volcanic deposits found offshore Japan ...

This situation is heating up. One of the world’s most volatile volcanoes is silently refilling with molten rock, sparking fears that this caldera could be getting ready to unleash a torrent of lava, ...

One of the most common features found at large volcanoes are calderas, formed by the collapse of the land due to eruption. The scale of these features varies a lot depending on if you're on Earth or ...

Krakatau, a volcanic island in Indonesia, killed more than 30,000 people when it erupted in 1883. One might assume that volcanic debris posed the major threat, yet many of the victims died from a ...
