Research Abstract |
We derived the seismic velocity and its temporal changes of Asama Volcano, Japan, where rich seismic dataset exists. We found a prominent low velocity body at depths of 5-10 km to the west of the summit. The low velocity body we found in this study has its diameter of 5 km or less, so that it has been impossible to detect with conventional seismic tomography techniques.
