Abstract
A geological zoning for landslides is performed in Kinki district, Southwest Japan, and 12 geological zones are obtained, as shown in Fig. 1 and Table 1 (in Japanese). The landslide areas are northern Tajima area (Zones 9 and 10), Sanda area (Zone 8), Awaji island (Zones 6 and 11), Izumi mountains (Zone 6) and Wakayama area (Zone 2 and 3). These zones are as follows:
Zone 2; ultrabasic and/or basic rocks
Zone 3; pre-retaceous geosynclinal sediments (metamorphosed facies)
Zone 6; Cretaceous marine sediments
Zone 8; Neogene non-arine or marine sediments
Zone 9; Neogene geosynclinal sediments and volcanic rocks (so-called “green tuff” area)
Zone 10; Pliocene-Quaternary terrestrial volcanics (lavas and pyroclastic rocks, associated with sediments)
Zone 11; Pliocene-Quaternary sediments (shallow sea or non-arine deposits)
