Estimating the Difficult-to-evacuate Population of Tsunami Disasters assuming Road Surface Conditions and Road Network Disruptions in the Snowy Cold Region
Abstract:The purpose of this study was to estimate the difficult-to-evacuate tsunami population caused by the Chishima Trench Earthquake, assuming that the road network would be disrupted in the event of a landslide. The study used walking speeds to zone difficult-to-evacuate locations during non-snowfall, snowfall, freezing, and heavy snowfall. It proposed a new estimation method for calculating the tsunami inundation population and the difficult-to-evacuate population using micro geodata (high-definition and micro sp… Show more
