A new practical landslide detection system was developed using only records from the existing seismograph network, Hi-net (High Sensitivity Seismograph Network, Japan), for disaster prevention management to rapidly detect sediment disasters. This was then applied in the Ohtou Landslide case, which occurred in Nara Prefecture, Japan on August 10, 2004. The estimated source point of ground-vibration was located within an error of approximately 1km away from the landslide, although the Hi-net stations were almost 15km away from the hypocenter. This result demonstrates that this application can be implemented for a new automated slope collapse detecting system for initial responses to a disaster in regions where landslides occur frequently such as in Japan.
