Research Interests:

There are various volcanoes on a continent crust which a plate is subducting like japan. For example, large stratovolcanoes, small stratovolcanoes, caldera volcanoes monogenetic volcano area, and etc. Volcanoes that are categorized into a type have some common features on composition and volume of erupted magmas and volcanic history. On the other hand, they also have individualties. I want to understand magmatic processes in the earth interior, universality and individuality of volcanoes, and mechanisms which govern variety of volcanoes. Furthermore, I want to establish a theory that predict long-term evolution of volcanoes.

Volcanic activities are governed by magmatic processes such as generation, segregation, upwelling, interaction with crust, and accumulation. The fact that volcanic diversity is large on continental crust suggests that crustal processes of magma are important for variety of volcanoes. Thus, I mainly study the crustal processes of magma and try to physically model melting and crystallization processes by interaction between magma and crust. Additionally, I petrologically investigate a natural caldera volcano (Aso volcano) as a case study because I think that we can see interaction between magma and crust more clearly in caldera volcanoes with voluminous magma. As the above, I aim to establish a model of igneous activity which is rational from physical and chemical points of view.
