 note = {On July 13, 2004, heavy rainfalls due to the intensive activities of rain front occurred in the Mid Niigata Region, Japan. They are as much as 400mm in 24 hours, bringing about serious flooding by breaking the river banks. The heavy rainfalls also triggered more than 3600 landslides. The floods and landslides in total claimed 15 lives, all of whom were characteristically old persons. Three months later of such hydrological disasters, the southern region of Mid Niigata Region was attacked by intensive earthquake of M.6.8 on Richter Scale on October 23, 2004. The main earthquake were followed by intensive after shocks which continued until December 2004. By these earthquakes, many landslides also occurred in the hilly and mountainous areas. Namely, different triggers for the landslides have been experienced in the similar geological and geomorphological region. Hence, we have classified the by 7.13 rainfall landslides into two types; surface failures and deep-seated slides with long-run mudflows. While, we have divided the 10.23 earthquake landslides into three types; surface failures, flow type slides and deep-seated slides.},
