Research interests

Earth is a colossal rock. Rocks consist of various sizes and kinds of minerals, which constitute diverse crystal structures and elements. Rocks and minerals are the essential unit forming solid planets and record planet history. We challenge to decipher information in the rocks and minerals to elucidate enigmas in formation and evolution of the planets

Now we especially study igneous activity which is one of the most important processes for formation and evolution of the planet . The igneous activity makes large scale structure of core-mantle, crusts, and volcanoes at the planet surface. We try to clarify igneous processes in and on the planets with field survey, observation of igneous rocks, chemical analyses, and theoretical study.

Photo aFCaldera view of Aso volcano from north caldera rim. The caldera with about 20 km diameter formed by the 90-ka catastrophic eruption. Mountains inside the caldera are volcanoes (central cones) after the 90-ka catastrophic eruption.

Photo b. Satsuma-Iwojima island. It is subaerial part of submarine Kikai caldera and has an active crater at present.

Current projects

  • Magma generation and eruption processes of caldera volcanoes
  • Machanisms governing diverse features of volcanoes
  • Formation processes of continental crust
  • Elucidation of volcanic eruption styles with observation of volcanic ejecta
  • Mechanisms of transportation and sedimentation of pyroclastic density current
  • Simulation of advection and diffusion of volcanic ash
