Window size of slope relief on susceptibility of earthquake induced landslides

The Tenth International Symposium on Mitigation of Geo-disasters in Asia Matsue Symposium Place: Shimane Civil Center, Matsue Date: 8 October 2012It is considered that the extent of damage due to the sediment related disaster induced landslides were influenced the scale of landslide. Meanwhile, the Scale of landslide was controlled by scale of slope. So, we investigated relationship between slope relief and scale of landslide using 3871 landslides data due to the Iwate and Miyagi inland earthquake in 2008. At result, landslide susceptibility was confirmed by using slope relief. Also it is important that slope relief with necessary window size was changed as to scale of landslide
