An MS5.0 earthquake occurred on February 11, 2016 in Xinyuan Country, Xinjiang, at a focal depth of 9 km. The earthquake intensity was VI degrees. Based on a field survey and a related data analysis, we reached two conclusions. First, the seismogenic structure producing this earthquake was located at the south margin of the Awulale mountain fault. The fault strike of is EW, the tendency is north and the dip is 20°~70°. There is a mutual influence between this fault and the Kashi River fault, which caused the Xinyuan-Hejing M6.6 earthquake on June 30, 2012. Second, most disasters caused by this earthquake were due to the fact that many buildings were old and the civil structure was self-built, not following any earthquake-resistant design. Therefore, after the earthquake, some buildings were unsafe.
