Volcanic Activity Research Group
We conduct research to reveal the eruption histories, magma evolution processes, and eruption mechanisms of active volcanoes. Much of our work is in cooperation with the Magmatic Activity Research Group and the Caldera Volcano Research Group. For the prediction of volcanic activity, it is important to understand the eruptive history and spatial distribution of active volcanoes in detail. We conduct geological surveys, and geochemical and geochronological studies of Tertiary and Quaternary volcanoes both on land and under the sea. We are also promoting the technological development of precise K-Ar and Ar/Ar dating of volcanic rocks, in particular for young samples. Our products include "Geological Map of Volcanoes", the database "Volcanoes of Japan", and also "Geological Map of Japan 1:200,000" and "Quadrangle series 1:50,000" around volcanoes. In case of an eruption, we conduct an urgent field survey in cooperation with the related researchers and organizations.

Expertise: Geochronology, Geochemistry
I am developing a high-precision K-Ar dating system using a sensitivity method and conducting K-Ar dating and geochemical research on Quaternary volcanic rocks.
Expertise: Volcano Geology, Petrology
I conduct research into the eruption and growth histories of active volcanoes and the formation and development process of the upper oceanic crust and island arc volcanoes, by combining field surveys, drilling core observations, chemical analysis, and historical document research.
Expertise: Volcano Geology, Petrology
I use petrology, geochemistry, and geochronology to investigate the processes and timescales of magma formation and eruption at active volcanoes in Japan and around the world. The core aims of my research are to constrain the eruption ages of volcanic rocks using 40Ar/39Ar dating, and to define the evolution of magma systems using microanalysis of volcanic crystals.
Expertise: Volcano Geology, Petrology
Through material science research on natural samples, I am studying the mid- to long-term history of volcanic eruptions, the processes of slab fluid ascent in subduction zones, and the generation, differentiation, mixing, and eruption of magma.
