The March 11, 2011 Tohoku earthquake tsunami disaster devastated the Pacific coast of northeastern part of Japan where the earthquake followed by tsunamis have took place in the past. The magnitude of the Tohoku earthquake was estimated to be 9.1, which is the largest in our Japanese history. The after shocks have still continued to happen around the earthquake source. The large number of casualties more than 19,500, which is the worst in Japan after World War II, and several types of tsunami impact such as inundation in a large area more than 500km2, destructive force destroying houses, buildings, infrastructures, road, and railways, and change of topography due to the erosion and deposition are reported. The issues to develop the tsunami disaster mitigation are identified.
The photo, videos and witness to record and report the tsunami attacking the coastal area, which should be compiled to know its feature. Although the observation system of tsunami were heavily damaged along the coast, some available data recorded by the tidal gages, GPS buoy one, and deep sea pressure sensors.
Principle for future tsunami hazard assumptions for developing tsunami countermeasures requires two levels of tsunamis; (1) Largest-possible tsunamis with extremely low possibility of occurrence but devastating once they occur. Place protection of people's lives as the first priority and establish comprehensive tsunami countermeasures embracing every possible instrument, while placing evacuation of residents as the core. (2) Tsunamis that occur frequently but cause major damage despite the relatively low tsunami height. Development of coastal protection facilities from the point view of protecting human life and the assets of residents, stabilizing the regional economy and securing efficient industrial bases.


Research field are numeral simulation for tsunami warning, human science for evacuation process, tsunami countermeasure; structure and non-structure
