Abstract
This presents a newly developed source model, composed of super asperities, for the 2011 off the Pacific coast of Tohoku, Japan, earthquake. Strong ground motions were simulated based on site amplification and phase characteristics. The constructed source model involves 9 super asperities, located off the coast of Miyagi through Ibaraki. There was good agreement between the observed and calculated ground motions, especially for the velocity waveforms (0.2-1.0 Hz) including near-source pulses.
