Abstract
A source model composed of super asperities was newly developed for the 2011 off the Pacific coast of Tohoku, Japan, earthquake and 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 off-the-coast of Ibaragi. The agreement between the observed and calculated ground motions was quite satisfactory, especially for velocity waveforms (0.2-1.0 Hz) including near-source pulses.
