Furthermore, the active faults and epicenters were mapped and 2 arc seismic belts, Bolnay-Baikal Seismic belt and Altay Seimsic Belt, and their 54 potential seismic sources are determined. Based on the data and results above mentioned the seismicity parameters, including b-value of G-R relations and annual average rate, v, for the two seismic belts and their potential sources were studied. Finally, the seismic zoning with different probability in China-Mongolia arc areas was carried out using China probabilistic hazard analysis method. By analyzing the data and results, we draw the following conclusions. Firstly, the origin of tectonic stress field in the study area is the collision and pressure of the India Plate to Eurasian Plate, passing from the Qinghai-Tibet Plateau. This is the reason why the seismicity is higher in the west than in the east, and all of earthquakes with magnitude 8 or greater occurred in the west. Secondly, the determination of the 2 arc seismic belts are reasonable in terms of their geotectonic location, geodynamic origin and seismicity characteristics. Finally, there are some differences between our results and the Mongolia Intensity Zoning map published in 1985 in terms of shape of seismic zoning map, especially in the areas near Ulaanbaatar. We argue that our results are reasonable if we take into account the data use of recent study of active faults and their parameters, so it can be used as a reference for seismic design.
