For decades, volcanologists believed that the primary trigger for explosive eruptions was a drop in pressure as magma rises toward the surface. When pressure falls, gases dissolved deep within the ...

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.

Tiny crystals suggest extinct volcanoes could still grow underground, a finding that could reshape how scientists assess eruption risk.

An eruption forecast is a probabilistic assessment of the likelihood and timing of volcanic activity. The forecast may also include information about the expected style of activity (Section 1.6), the ...

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 ...
