摘要

Using the earthquake catalogues from China and Mongolia and supplemented by the global earthquake catalogue, the uniform catalogue of North China, Mongolia, and adjacent areas has been established for the seismic hazard analysis as well as the seismic zoning of Mongolia according to the determined principles. Based on the uniform catalogue, the seismicity of the North China, Mongolia, and adjacent areas have been analyzed, and the following conclusions are made. 1) The epicenter map can be roughly divided into two parts by the longitude line 105°E, which is in accordance with the "North-South Seismic Belt" of China. The seismicity is in a high level with many strong earthquakes in the west and is in a low level with little strong events in the east. 2) Most earthquakes are shallow-focus events in the study area. 3) Earthquakes with magnitude greater than 5 are basically complete since 1450 A.D. 4) Two seismic belts, Altay seismic belt and Bolnay-Baikal seismic belt, are determined according to the epicenters and tectonics. 5) The b-values of magnitude-frequency relationship for the whole areas are between 0.6 and 0.7, 0.677 for the Altay seismic belt and 0.699 for the Bolnay-Baikal seismic belt.
