Visualization of Strong Ground Motion and Tsunami for the Great Earthquake of 2011 Off Tohoku, Japan
SESSION: Invited Talks 1
EVENT TYPE: Invited Speakers
TIME: 11:15AM - 12:00PM
SESSION CHAIR: William Kramer
Presenter(s):Takashi Furumura
ROOM:Mile High
ABSTRACT:
The strong impact caused by the 2011 earthquake off Tohoku, Japan, (Mw=9.0) was reproduced by a large-scale FDM simulation using the K-Computer and the Earth Simulator with a detail earthquake source rupture model and a heterogeneous subsurface structure model. The visualized derived seismic wavefield illustrates the significance of this earthquake and the process in which large and long-duration ground motion is developed in populated cities and destructive tsunami is amplified along the Tohoku coast. The results of the simulation are compared the synthetic and observed waveforms from high-density nation-wide seismic network and offshore ocean bottom tsunami network both deployed over Japan. We believe the reliable disaster information should be effective in earthquake disaster reduction studies. Towards this goal, the development of integrated earthquake disaster prevention simulations by linking sequences of simulations for earthquake nucleation, seismic wave and tsunami propagation, and building oscillation in interaction with soft soil is presented.
