[J04-6-01] Developing a Rapid Tsunami Response System: Application to South America Region
Using high-performance computing and spatial information science, an advanced method of tsunami inundation forecasting and mapping can be developed to enhance real-time disaster response.
Given the maximum tsunami height and flow depth distribution, we perform quantitative estimation of exposed population using global population data, and the numbers of potential death by applying tsunami fragility curve. The prototype system under development is focused on South American region. In the trial operation, we verify the capability of the method as a new tsunami response system for three major tsunami-prone cities, Tumaco in the southern pacific coast of Colombia, Lima in the central coast of Peru, and Iquique in the northern coast of Chile. The bathymetry and topography data for the target cities were provided under the SATREPS project frameworks between Japan and the respective countries.
The tsunami simulation is based on the TUNAMI code developed by Tohoku University, Japan. The nested grid system for the bathymetry and topography data varies from 27 arc-second to 10 m resolution for the regional propagation and local inundation modeling, respectively. The global population data is taken form LandScan 2011 model. The mapping result and web publication are constructed using open-software, Generic Mapping Tools and Python Programing Language, respectively. The preliminary tests of the proposed system show promising result. The average total computational time for all regions is approximately 35 minutes.
