Real-time magma tomography-Basic research for sources and analysis

We have conducted a research on the feasibility of volcano monitoring, in which a seismic source with high accuracy are used. We examined the efficiency of monitoring at Sakurajima volcano, Japan, using a dataset of seismic exploration, and showed that the monitoring with the existing seismic source is possible for Sakurajima volcano. We also showed the usefulness of a linear-moving low-frequency vibrator, which will be used for highly heterogeneous structure of volcanoes.
