Description :

An earthquake with a moment magnitude of 7.0 occurred in northern Japan on May 26, 2003. Landslides were triggered by the earthquake, and among which a massive landslide occurred in the Tsukidate area, northwest of Sendai, the capital city of Miyagi Prefecture. The Tsukidate landslide partially destroyed two houses. Although two people were partially buried by the displaced landslide mass, both were subsequently rescued. The landslide was triggered on a gentle slope with the sliding surface inclination of approximately 13.5 degrees. The displaced landslide mass traveled a long distance of about 130 m, and finally spread and deposited on a horizontal rice paddy, thus showing some typical characteristics of rapid long traveling flow phenomenon. Because this landslide was triggered by an earthquake without rainfall, the fluidization behavior of the landslide attracted the attention of researchers in various fields.
