Abstract
 GIS Analyses of the Landslides in 2004, Mid Niigata Track: Mining and Geosciences Author(s): Hiromitsu Yamagishi, Toko Takayama, Junko Iwahashi In 2004, heavy rainfalls and intensive earthquakes triggered numberless landslides in Mid Niigata, Japan. Using ArcInfo, we have analyzed and compared in distribution, related to geology and geomorphology, between the two events. As the results, we have found that the landslide density, and geologic facies where the landslides are concentrated, are remarkably different.
