The Hoppo landslide area is underlain by the Miocene “Green tuff layers” partially covered by the Plio-Pleistocene volcanic rocks and the Pleistocene and Recent debris. Those layers and debris are partially and severely altered to characteristic clays in solfataric areas. The clay minerals in this area are mainly composed of Montomorillonite and kaolinte.Two types of landslides can be identified on the location of slide surfaces in geologic cross sections. One of them is a type of debris slides in which the slide surfaces are observed in the debris or along the altered clay layers between the debris and “Green tuff” or the volcanics. In another type of slides, the slide surfaces or potential surface of slide are considered to locate in the “Green tuff layers”.
