Research Abstract

The 2011 off the Pacific coast of Tohoku earthquake occurred offshore of northeast Japan region on March 11, 2011, and large ground motion with long duration and huge tsunami damaged human society. To clarify the generation mechanism of this large earthquake, we carried out various observations. Seismic observations in marine and land areas revealed variation of seismic activities in time and space. Geometry of the source was estimated by seismic surveys and ocean bottom crustal movement measurements. In addition, the slip distribution during the mainshock was obtained using various geophysical datasets. Field surveys revealed tsunamis and the generation process of the tsunamis was estimated. Damage of constructions was also clarified and useful information for disaster mitigation in future was obtained.
