Crustal Activity Information
We have been constructing a database of seismic activity, crustal movement and other geophysical observations, through exchanging seismic data with other universities and national researchﾂꀀ agencies. Information for earthquake generating properties, crustal activity and long-term earthquake potential has been assessed based on the research using the database. The database contains information on the seismicity in southwest Japan, structural properties in earthquake source areas, space-time variations of earthquake generating properties. We also plan and execute basic surveys of tectonic structures and active faults.
