the causes of the disaster occurrence
including geology
relief
climate and human activities
were analyzed.The main cause to the occurrence was the heavy rainstorm.The amount of daily rainfall was over 88 mm on August 12.The trend of debris flow activities was analyzed by referring to historical debris flow.Controlling countermeasures such as emergency measures and upper mitigation measures are presented through comparing the 050811 hazard with other hazards like the debris flow in Xinping County.
