US-JAPAN COLLABORATIVE RESEARCH ON THE MARCH 11, 2011 EARTHQUAKE, TSUNAMI INUNDATION AND INITIAL SPREAD OF FUKUSHIMA RADIONUCLIDES INTO THE PACIFIC OCEAN

A team of US and Japanese investigators has developed a high-resolution global-Japan coastal coupled WRF/FVCOM system to simulate the March 11 M9 earthquake, tsunami wave generation, propagation, coastal inundation along northern Honshu Island, and initial spread of Fukushima Dai-ichi Cs-137 across the shelf to deeper water. The Japan coastal model includes the earthquake generation zone with finer grid resolution over the inner shelf and inundation zone (down to 5 m near Fukushima Dai-ichi), with boundary and surface forcing provided by the global WRF/FVCOM. The model hindcasts will start with the initial March 11 earthquake bottom movement (provided by three advanced seismic models) through mid-April. During this period, Cs-137 source concentration levels have peaked and decreased towards increasing coastal and offshelf concentration levels, indicative of cross-shelf transport and shelf-ocean exchange processes, with a potential sedimentation loss and biological accumulation in the nearshore region. Initial model comparisons of simulated water level with coastal tide gauge and inundation extend data show good agreement. The model system will be described and preliminary results presented.
