Proposal of Conditional Seismic Hazard Maps for Site Consideration of Disaster Base Buildings

Abstract

Considering the desirability of constructing disaster base buildings in areas with a low risk of being affected by the same disaster as the main base, this paper proposed a conditional seismic hazard map that assumes the seismic intensity at the main base exceeds a certain level. We evaluated areas with a low probability of simultaneous impact on main bases and disaster base building using conditional seismic hazard maps for Tokyo, Osaka, and Nagoya. As a result, if the location were to be situated near Chiyoda Ward, Tokyo, the area around Nerima Ward would be a candidate location, while the western part of Kobe City was selected as a candidate location for central Osaka. For Nagoya, areas near Komaki City and Nagakute City were selected as candidate locations.
