Verification of evacuation range in Misa Oita-shi using geospatial information at tsunami

Abstract

We aim to analyze and evaluate an evacuation range in Misa Oita-shi using three-dimensional geospatial information at the time of tsunami caused by the earthquake in Beppu Bay and the Nankai Trough. In addition, the analysis and evaluation are performed separately for healthy and vulnerable people. Features of our research are considering evacuation to a safe height of tsunami evacuation building and the distance to a connecting point of road network from the building. As a result of the analysis and evaluation, we indicate that all residents of Misa area including vulnerable people can evacuate from Beppu Bay Tsunami if every tsunami evacuation building is able to be used.
