In September 2011, numerous deep-seated landslides accompanied with landslide dams were triggered by the torrential rain over the Kii Peninsula. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) conducted surveys based on the Sediment Disaster Prevention Act. At the initial stage of the emergency, the MLIT successfully found the landslide dams in the damaged area through analyzing the satellite SAR imagery. In this paper, we report the situation of the surveys that conducted during the disaster.
