Research Abstract

Effect of source and site on generation of extreme ground motions are studied. The area with higher stress drop or higher slip velocity on the source fault and rupture propagation controlled near-source strong ground motions. Non-linear site response affected extreme ground motion generation at the Anamizu station during the 2007 Noto-Hanto earthquake and the Ichinoseki-Nishi station during the 2008 Iwate-Miyagi earthquake. Depth dependence of stress drop on SMGA are found and it could be an useful parameter of the source model for prediction of strong ground motions.
