Typhoon "Rusa" (No.0215) attacked the Republic of Korea from August 31 to September 1, 2002. Depended on this typhoon, the heavy rainfall was brought through the Korean Peninsula. In Particularly, 100mm of hourly precipitation and 870mm of one day precipitation were recorded on August 31 in Kangnung where is located in the north-east of Korea. The accumulated precipitation at Kangnung amounted to 898mm from August 30 to September 1. During heavy rainfall, many slope failures occurred. The one failured slope was investigated in this study to make clear the mechanism of slope failure with special attention to clay veins developed on it by means of X-ray diffraction, optical microscope, scanning electron microscope, transmission electron microscope and computer simulation.
