| 摘 要： | 本文用模式识别申修改的CORA—3方法和加权的HammilLg方法,对青海地区大量的地质、地貌、地球物理及地震资料进行了分析和研究,分别判定出了该地区6.0、6.5和7.0级地震的潜在震源区,并定量地给出了整体识别的可信度和每个潜在震源区的危险概率。1988年11月5日唐古拉6.8级和1990年1月14日茫崖6.7级地震均发生在本文圈定的潜在震源区内。

| Abstract: | In this paper,by using the revised CORA-3 and weighted Hamming methods of pattern recognition,based on the analysis and study of geological,geomorphological,geophysical and seismological data in Qinghai area,the M6.0,M6.5 and M7.0 potential earthquake source zones are divided respectively in this area.The confidence level for whole recognition and danger probability for each potential earthquake source zone are given quantitatively.The M6.8 Tanggula earthquake on Nov.5,1988 and the M6.7 Mangya earthquake on Jan.14,1990 are all within the potential earthquake source zones divided by this paper. |
