[MIS34-04] Strain concentration zone based on GNSS data in southwest Japan and its possible application to a long-term forecast of inland earthquakes
Keywords:Strain concentration zone, GNSS, Inland earthquake
Most large earthquakes including the 2016 Kumamoto earthquake occur in the area of high rate of the maximum shear strain rate (Figure). Because the geodetically observed strain rate includes both elastic and inelastic strain, the strain rate is not directly related with an occurrence rate of earthquakes. However, the geodetic strain rate is an important data apparently related with earthquakes. It should be used as one of datasets to evaluate a long-term forecasting model of large earthquakes in the Japanese Islands.
