Assessment of Tsunami Inundation Exposure of Energy-Related Base Facilities Caused by Anticipated Nankai Megathrust Earthquakes

摘要

Exposure assessment was done for energy-related base facilities exposed to tsunami inundation caused by the anticipated megathrust earthquakes along the Nankai trough subduction zones. The distribution maps of tsunami inundation depth used in this study were predicted by the Cabinet Office, Government of Japan. By overlaying those maps on the distribution maps of thermal power generation plants and LNG storage tanks, exposure levels were evaluated in terms of power generation capacities or storage capacities.
