Abstract

This paper is results of analyzing causes of damage and rainfall characteristics to investigate characteristics of landslide occurrence and its causes at Inje area in Gangwondo around July in 2006 through collection of related data, literature review and field reconnaissance. From results of analyzing the geometrical characteristics of landslide slope, the slope width of showing the most probable frequency were in the range of 10~50m and the most frequent slope angle was in the range of $30{\sim}40^{\circ}$. The most probable elevation of slope was 200~300m. For the slope direction of landslides, the most frequent directions were NW and SE.
