A large-scale landslide near the Aratozawa dam reservoir was occurred when the 2008 Iwate-Miyagi Nairiku earthquake with magnitude of 7.2 hit the area of Mount Kurikoma in Miyagi Prefecture of Japan. The epicenter of the earthquake was located about 10 km northeast part of Mount Kurikoma, at the border between Miyagi Prefecture and Iwate Prefecture. This paper highlights site investigation and sampling of the Aratozawa landslide, following with the laboratory experiment by means of undrained dynamic loading ring shear apparatus. In addition, to understand the initiation mechanism, landslide simulation using the LS-RAPID model was carried out. By combining the ring shear test results and LS-RAPID, the Aratozawa landslide process from pre-failure state, failure initiation, post-failure motion up to deposition stage are well described. The result of this study contributes to the landslide hazard assessment, particularly for the case of landslides near reservoir where earthquake, rainfall and or reservoir impoundment are considered as single or combined triggering factors.
