| Abstract | The 2008 Iwate-Miyagi Nairiku Earthquake with a magnitude 7.2 induced numerous slope failures on steep inner valleys along the Ichihasama River, the Nihasama River and the Sanhasama River in Miyagi Prefecture, Japan. The debris mass rushed down the steep slopes and deposited in the valley, resulting in many landslide dams generating along the rivers. The purpose of this study is to clarify the topographic and geological features of slope failures and landslide dams generated by the earthquakes using by the aerial photointerpretaion. There are many failed slopes on acid tuff breccias of pyroclastic rocks. Many landslide dams were generated by occurrence of slope failures near the river courses. Most failed slopes that formed the main landslide dams are at a distance of approximately 250m from the center of the river course. |
