About Usu Volcano

About Miyakejima Volcano

• My study
  To understand a magma-feeding system beneath a volcano
  1. Petrography and Petrology
     • Evolution of a magma-feeding system beneath Usu Volcano, Japan
       e.g., Detailed description of phenocrysts (EPMA, SIMS); textural analysis (CSD = Crystal Size Distribution); etc..
  2. Experimental Petrology
     • High-pressure melting experiments for a product from Usu Volcano
       -> Estimation of the depth of the magma chamber
     • Estimation of diffusion coefficients and elemental distribution coefficients of rock-forming minerals
  3. Physical Volcanology
     • Dynamics of a volcanic eruption (Fluid-mechanical model)
     • Thermal model of a magma-feeding system
