Abstract：On September 23rd, 2016, the MS4.9 and MS5.1 earthquakes respectively occurred at Litang county of Sichuan province. During the process on the emergency disposal and intensity sketch, the background information on post-earthquake field has an important function. Batang fracture and Litang fracture both exist in the area, and it is possible that a group of extensional normal fault with en echelon arrangement will be formed, and also the earthquake of swarm earthquake type and double earthquake type will occur easily. In addition, in the high and cold areas with the special geographical conditions, the historical research results on local earthquake and earthquake mechanism data concerned can be used as basis to determine seismogenic structure and assist to sketch the isoseismal of earthquake field.
