THE CHARACTERIZING MODEL FOR TSUNAMI SOURCE REGARDING THE INTER-PLATE EARTHQUAKE TSUNAMI

Abstract

The 2011 Tohoku Earthquake which exceeds the maximum magnitude of historical earthquake records could not be predicted. Which means, in the probabilistic tsunami hazard assessment for the future prediction, it is necessary to apply a different concept from the existing scenario tsunami assessment based on the maximum magnitude of historical earthquake tsunami. As a new modeling method for scenario tsunami, we propose a characterized tsunami source model which indicates setting method of the area of tsunami source and slip distribution by the inter-plate earthquake.
