Application of Emergency Response Difficulty Coefficient Developed by Tokyo Metropolitan Government for Seismic Community Risk Assessment to Korea

Abstract

The extent of damage to a community from an earthquake depends on the existing road infrastructure and space for disaster response activities. The Bureau of Urban Development of the Tokyo Metropolitan Government has assessed the seismic vulnerability and risk to communities, and announced the results approximately every five years since 1975. The present study investigates the assessment methods used last three times by focusing on the emergency response difficulty coefficient. The methods are then applied to a community in the Republic of Korea as a pilot. Subsequently, it is observed that the results of application in Korea are similar to those in the Tokyo Metropolitan city.
