VALIDITY OF STRONG MOTION PREDICTION RECIPE FOR INLAND-CRUST EARTHQUAKES
Ground motions from inland-crust earthquakes are simulated using a characterized source model with asperities in an entire rupture area. The characterized model is constructed based on the recipe we proposed. Validity and applicability of the recipe has been examined by comparing observed ground motions with synthesized ones for recent disastrous earthquakes. We show a case of the 2007 Chuetsu-oki (Mw 6.6) as one of examples.This earthquake occurred very close to the Kasiwazaki-Kariwa Nuclear Power Plant. Ground motions from this earthquake are well simulated based on the characterized source model. We find the recipe is useful for predicting design ground motions for earthquake safety designs as long as the source fault is specified through investigation of active folds and faults and the fault parameters are given considering regional characteristics.
