Estimation of the Number of Demolished Wooden Houses based on the Damage Dataset after the 1995 Kobe Earthquake

Abstract

This study evaluates the number of demolished wooden houses after the scenario Tokyo Metropolitan earthquake. The building dataset compiled by Kobe City Government after the 1995 Kobe earthquake was employed to achieve the objective. A method to estimate the number of demolished wooden houses due to ground shaking is developed considering the spatial distribution of the JMA (Japan Meteorological Agency) seismic intensity. The result after the 1995 Kobe earthquake was compared with that after the 2004 Mid Niigata earthquake, and the difference between the two events was not significant. Lastly, the method was applied for the scenario Tokyo Metropolitan earthquake to estimate the number of demolished wooden houses.
