Abstract

Accurate applicability of hard and soft countermeasures against the 2011 Tohoku Earthquake Tsunami is still under survey. Tide stations located in the coasts were completely washed out and no tide record is obtained in the area devastated by the tsunami with more than 10m height. Only offshore buoy observation data is analyzed employing signal directly stored in memories in the station. Detail tsunami inundation and run up heights were obtained in teams dispatched by the 2011 Tohoku Earthquake Tsunami Joint Survey Group on the March. The paper describes the tsunami heights and hazard characteristics obtained in the coast of Miyagi prefecture, one of devastated areas due to the huge tsunami. Some hints to reduce the tsunami impulsive pressures are discussed.
