| The large earthquake, the Iwate-Miyagi Nairiku Earthquake in 2008 mainly struck the mid Tohoku Region in northeastern Honshu Island, Japan on June 14, 2008. The magnitude of the event was estimated as 7.2 in the JMA scale. Based on the results of the emergency inspections of 134 dams by the site officers immediately after the earthquake, on June 15 and 16, dam engineering experts carried out site investigation at the five dams where damage had been found. This paper described the outlines of the results of the preliminary investigations of the five dams. According to the investigation, no problems severe enough to threaten the structural safety of any of the five dams were found. This verified the high level of seismic resistance of the dams in Japan. |
