Accessibility to cultural heritages in road blockade conditions caused by earthquakes

―Road blockade simulations based on estimated age and structure of buildings―

Abstract

The purpose of this study is to evaluate accessibility to cultural heritages in road blockade caused by earthquakes in Kyoto City. In order to predict accurate road blockade distributions, we construct a simulation model to estimate detailed attributes of each building by combining multiple data sets and thereafter simulate the collapses based on them. As a result, 8% of cultural heritages cannot be reached at all and another 8% at only 20% due to the blockade. These results suggest approximately 20% of cultural heritages are at high risk of being burned out by fire disasters and therefore, disaster mitigation strategies such as on-site fire extinguishers are needed.
