| Outline of Final Research Achievements |
Three type earthquakes; active-fault, trench-type, and intra-slab earthquakes are clarified to occur successively, by analyzing pre-existing data of these earthquakes. Active- fault and intra-slab earthquakes also occurred after the 2011 off the Pacific coast of Tohoku Earthquake.
Analysis of earthquake motion around active faults before and after a trench-type earthquake are conducted for potential faults, which have a high risk of earthquake generation, by the pseudo-3D fault motion simulation of considering a fault process zone, and it successive movement of the active fault and the earthquake interlocking are confirmed.
