Abstract
An earthquake measuring 7.0 on the Richter scale occurred in Lushan County in Southwest China’s Sichuan Province, at 8:02 A.M, on 20 April 2013. A total number of 217 people were reported dead or missing, and 13,000 people were injured due to the earthquake. Shortly after the earthquake, a group from China Geological Survey carried out field investigations in the earthquake-hit region of Lushan County, Baoxing County and Tianquan County. The results showed that 539 landslides were triggered by the earthquake in the study area. Among them, small and medium-scale landslides with volume ranging from several cubic meters to a few tens of thousand cubic meters were in the majority. These earthquake-triggered landslides were distributed primarily along the causative faults of Shuangshi-Dachuan Fault and most of them occurred within the buffer zone of −20 to 20 km distance to the causative fault.
