SELECT TSUNAMI BY CONSIDERING THE CUMULATIVE PROBABILITY OF OCCURRENCE IN COASTS OF THE JAPAN SEA OF HOKKAIDO

Abstract

 It necessary to set relatively high frequency tsunami for preservation of coastal facilities.We called this tsunami "tsunami for designing". However, tsunami was occur less frequently, and different characteristic, history by each region. Suzuki et al., tryed to set "tsunami for designing" that focus to average occurence interval of earthquake by Headquarters for Earthquake Research Promotion, proposed the method that used comulative incidence rate of tsunami. In this study, targets Japan Sea side of Hokkaido that has be character that considerably lower frequency of earthquake than ocean-trench earthquake, and have be many active fault. We verificated applicability of this method on Japan Sea side of Hokkaido.
