Behavior of dams due to the Western Tottori Prefecture earthquake in 2000

The Western Tottori Prefecture earthquake of October 6, 2000, caused strong earthquake motion over a wide area. Immediately after the earthquake, dam management personnel carried out special safety inspections of dam facilities in the region. Research engineers of the Public Works Research Institute (PWRI) performed a field investigation of dams near the epicenter and gathered earthquake observation data on these dams. The results of the special safety inspections by the dam site offices and the field investigation by PWRI confirmed that no damage causing harm to dam safety occurred.
