Outline of Final Research Achievements

Distribution of seismogenic source faults is the most significant information for the estimation of seismic hazards. For the detection of buried fault structures with a uniform precision, our gravity database of the Japanese Islands is recompiled.
In order to fill up the blank area of gravity measurements, we conducted an extensive gravity survey. In particular in the Hokkaido district, more than 1,600 gravity stations are added to our newest database.
