Qushi and Zhonghe villages and towns in the central and northern part of Tengchong County. This event triggered landslide and debris flow disasters over a large area. During the catastrophe

nine local residents were killed or disappeared and nearly 136 million RMB of properties damage occurred. This study shows that the rainstorm

with rainfall of 159.6 mm within 24 hours and reoccurring frequency of 60 years

was the main cause of the disaster. Based on the characteristics of the area

the current situation and the tendency for geological hazards to develop

eleven mitigation measures currently in place or possible in the future are put forward.
