| This paper purposes to modeling earthquake-induced deep-seated landslides， focusing on pre-existing landslide topographies by using logistic regression analysis based on the date from the Mid-Niigata earthquake in 2004 and the Iwate-Miyagi Inland earthquake in 2008. We focused on pre-existing landslide topographies， according to the result that more landslides occurred within pre-exiting landslide topographies by the Mid-Niigata earthquake (Has et al.， 2009)， and the landslide topographical interpretation is relatively easy and such data are available in Japan (e.g. NIED， 2010). The result of this paper suggested the logistic regression analysis is useful method to evaluate earthquake-induced deep-seated landslide within pre-existing landslide topography. |
