内容記述 Earthquakes damage physical assets, such as houses, public infrastructure, fields, factories, facilities, as well as inventory of timbers, crops, or products. A direct damage amount is the primary evidence for financial measures to restore and reconstruct the affected ar-eas. Therefore, from a policy perspective, it is essen-tial to estimate it quickly and accurately. Cui et al. have proposed a simple method for estimating direct damages [1, 2]. This study aimed to build a prototype of automatic estimation system and discuss its social implementation. As a result, we succeeded in estimating three earthquakes ? the 2018 Osaka Prefecture Northern Earthquake, 2018 Hokkaido Iburi Earth-quake, and 2019 Yamagata-oki Earthquake ? damage amounts automatically and defining some technical re-quirements for development. On the other hand, it is necessary to replace the Minryoku index, which is used for Cui’s estimation method and no longer be-ing updated, by new physical assets quantity index, which is continuously updatable. Moreover, the estimation accuracy must be evaluated and improved in finer units of space.
