| Based on aerial photographic interpretation、 we analyzed the landslides induced by the Iwate-Miyagi Inland earthquake in 2008. A total of 136 landslides interpreted from the study area、 most of the landslides (97.1%) occurred on the hanging wall. The analyzed results showed that reverse fault earthquake induce more landslides on the hanging-wall of source fault. The distance from source fault、 distance from the epicenter and PGA distribution were considered to act as factors to control the distribution of landslides. The results suggested that in cases of similar magnitude earthquakes、 above factors are considerable to be used for estimation of earthquake-induced landslides distribution. |
