BASIC EXAMINATION OF APPLICABILITY OF GR LAW IN PROBABILISTIC TSUNAMI HAZARD ASSESSMENT

Abstract

 Although two tsunami levels are set for disaster protection and prevention, in order to make measures precisely stepwise and implement those, and furthermore to calculate the expected value for cost benefit, the scale and the probability of tsunamis are necessary from low frequency to high frequency. This study examined the applicability of the Gutenberg - Richter low showing the probability of earthquake to the tsunami probability evaluation with incorporating a rate of earthquake occurrence to tsunami occurrence in each magnitude of earthquake. The tsunami probability based on the Gutenberg-Richter low and the tsunami height were comparing with the result of the logic tree method and the extreme statistic. It is summarized that possibility of applying Gutenberg-Richter rule for high frequency probability of tsunami and future works of low frequency that.
