Introduction model of the 2011 Tohoku earthquake that reproduces both long- period (20–100 s) and short-period (3–20 s) ground motions. In The 11 March 2011, Mw 9 Tohoku earthquake order to reproduce the observed large slip area (slip asperity), we assign a large D (slip critical distance) area following kinematic c occurred in the subduction zone between the Pacific source inversion results. Sufficiently large slip is achieved through and North American Plates in northeastern Honshu, rupture reactivation by the double-slip-weakening friction model. Japan. This giant event was recorded by a vast Global In order to reproduce the strong-motion generation areas (SMGAs), we assign short D and large stress-drop areas following empirical Positioning System (GPS) and seismic network. The Green’s function (EGF) simulation results, which indicate that, Tohoku earthquake featured complex rupture patterns although more distant from the hypocenter, SMGA1 ruptured involving multiple
