Caldera Volcano Research Group

Caldera Volcano Research Group explores large-scale eruptions which produce voluminous ignimbrite and collapse caldera. Our researches target the evolution of magma plumbing system toward catastrophic eruption, sequence of caldera-forming eruption, and the impact of eruption on the environments, making full use of the geological, petrological and geophysical methods. These researches are carried in collaboration with Volcanic Activity Research Group and Magmatic Activity Research Group.

Magma ascent, degassing, eruption processes on active volcanoes and present condition and evolution of their magma plumbing systems are investigated based on petrological studies of volcanic rocks and melt inclusion analyses.
