Many researches employed several landslide-related factors such as the slope-aspect, size, lithology etc. to study the landslide assessment. Utilizing the landslide inventory delineated by 1:5000 high resolution aerial photo, this article explored the landslide characteristics, such as the landslide area, slump direction and air current for two different rock types in Kaoping River basin during the period of 2009 Typhoon Morakot. It is found that the air current direction is the dominant factor for landslides triggered by a heavy rainfall in Kaoping River basin. The number and size of landslides in slate is larger than the sedimentary rock. This indicates the slate region in Kaoping River basin is more likely to take place landslide; however, the landslide characteristic in size distribution is similar.
