Title: Strong Ground Motion Simulations of the M7.1 Kumamoto, Japan Earthquake Using Characterized Heterogeneous Source Models

Abstract

The objective of our study is to analyze the performance of characterized heterogeneous rupture models in simulations of near-fault ground motion from the M7 Kumamoto, Japan earthquake, using Graves and Pitarka (2016) broad-band simulation method. We developed a kinematic earthquake rupture generator that combines the Graves and Pitarka (2016) (GP2016) rupture model with the multiple asperity characterized rupture model of Irikura and Miyake (IM2011), also known as Irikura recipe (Irikura and Miyake, 2011). The proposed kinematic rupture model incorporates distinct features of both original rupture models such as small-scale stochastic rupture variability, and shallow areas with large slip separated from areas with high sliprate, inherited from the GP2016, and desired near-fault large-scale rupture directivity effects produced by the multiple asperity model IM2011.
