EFFECTS OF THE MODEL FOR SCENARIO TSUNAMI ON THE PROBABILISTIC TSUNAMI HAZARD ASSESSMENT

Abstract

The 2011 Tohoku Earthquake exceeded the maximum magnitude of historical earthquakes. After the earthquake, new methods and models for scenario tsunamis have been proposed. We applied one of them to the inter-plate earthquake tsunamis along the Chishima-Japan Trench, and showed the effects of treating uncertainties in the scenario tsunamis on the probabilistic tsunami hazard assessment by comparing the results with those using the conventional model based on the maximum magnitude of historical earthquake tsunami.
