Abstract

We propose a method of using satellite images to analyze road conditions after a large-scale earthquake accompanied by a tsunami. Remote sensing using satellite images can be used to collect information over a wide area in a short time. Such information is particularly valuable for organizing relief efforts quickly and effectively after large-scale disasters such as the Great East Japan Earthquake on March 11, 2011. Although a large number of studies have focused on the extraction of damaged buildings and debris on roads, there have been few studies on the extraction of road areas flooded by a tsunami. Also, since the Great East Japan Earthquake, there has been increased concern about tsunami damage in addition to earthquake damage, meaning that a method of extracting both earthquake damage and tsunami damage is required. The purpose of this study is to analyze the safety of roads around a stricken area in detail to help support relief activities during times of disasters.
