Landslide density distributions and geologic formations. (A) Map showing geologic formations with >10% by area high landslide density and with >10% by area absent landslides. (B) Chart showing formations with >10% by area with high landslide density. Ku—granodiorite; Thp—hornblende quartz diorite; Kap—basalt lava and tuffaceous sandstone; Kco—basaltic lava and volcanic breccia; TKdi—diorite; Trhp—rhyodacite porphyry; Kav—andesitic lava; Kmam—andesite lava and volcanic sandstone and siltstone; TKn—crystal tuff and tuffaceous clastics; Kln—basaltic breccia and basalt lava; Kja—amphibolite; Kper—basalt lava and tuff, volcanic sandstone (Bawiec, 1998).
