Abstract

It is well known that large thrust-type earthquakes have occurred along the plate boundary around the Japan Islands with a recurrence interval of 100 to 150 years. For long-term prediction of the earthquakes, it is necessary to construct an adequate earthquake cycle model along with a continuous observation of seismic activity, crustal deformation and investigation of the historical documents. Now, we developed GeoFEM module under the collaborative work between Nagoya University and RIST. In this study, we simulate an earthquake cycle and its associated geophysical phenomena in northeast Japan using GeoFEM based on the kinematic model to evaluate the crustal deformations and stress changes in inland region.
