Possibility of Tsunami Risk Map Based on Extreme Value Analysis with Historical Records

Though Japan has prepared tsunami hazard map about last 10 years, ‘The 2011 off the Pacific Coast of Tohoku Earthquake’ ( called Tohoku Earthquake in this paper after here), caused bigger tsunami than that in distributed hazard maps in many area. This is the main reason why we had much number of victims. In case we know the much information of a plate at and around epicenter near target area, we can estimate the tsunami risk from the probability of fault slips directly. If there are small numbers of the information of that, we need another risk analysis method. This paper shows a method and results of a tsunami risk map employed by statistical extreme value analysis with historical records of tsunami heights.
