Development of Real-Time Earthquake Damage Information System in Japan

Abstract eng:
It is extremely important to quickly assess the damage immediately after an earthquake for providing suitable disaster response. We has constructed prototype of a real-time earthquake damage information system for appropriate decisionmaking regarding the initial response at an earlier stage immediately after an earthquake by combining amplification characteristic data for subsurface ground as well as basic data such as population and building information and observation data including real-time strong-motion data observed by K-NET and KiK-net. We report on our progress in building a database containing building models covering the entire country of Japan, along with the development of methodologies related to damage estimation and situation assessment, continuous strong motion observation, and system architecture construction, which are necessary components of a real-time earthquake damage information system. This system is intended to assist in making initial response decisions immediately after a disaster, and is expected to estimate and assess the overall condition of damage in real time even in the case of a disaster over a wide area, such as a large earthquake.
