Magmatic fluid from magma reservoir causes various phenomena such as earthquakes, crustal deformation, and surface phenomena such as eruptions. However, these processes and their relation to magmatic fluid have not been fully understood. Based on seismic observation data, we are trying to understand subsurface structure of magma reservoirs and mechanism of volcanic earthquakes. Furthermore, we try to understand the magma feeding system from lower part of crust to shallow level, by analysis of low-frequency earthquakes and volcanic tremor. We also aim to develop monitoring tools to understand the internal conditions of volcanoes, based on seismic observation data such as ambient noise and seismic activity.
