分析认为此次地震发生在巴颜喀拉块体内部，发震构造为江错断裂。根据地震地

Analysis believes that the earthquake occurred inside the Bayan Har block and the seismogenic structure is the Jiangcuo fault. According to a comprehensive survey of the scale and length of the earthquake surface rupture and the damage of buildings, it is believed that the Langma Jiaheri area has large surface ruptures, good continuity of the rupture zone, and development of multiple types of seismic surface ruptures. The area can be preliminarily determined as The macroscopic epicenter, the geographical coordinates are: 34.736°N, 97.794°E.

The analysis shows that the earthquake occurred in Bayankala block, and the seismogenic structure is Jiangcuo fault. According to the comprehensive investigation of the scale, length and building damage of the earthquake surface rupture, it is considered that the surface rupture in Langma jiaheli area has large scale, good continuity of the rupture zone and many types of earthquake surface rupture. The area can be preliminarily determined as the macro epicenter, and the geographical coordinate is 34.736 ° N,97.794 ° E。<br>
