摘要
潜在震源区的判定是地震危险性分析工作的基础,潜在震源的准确性直接影响着地震危险性分析的结果的合理与否;本文采用多维实测数据类似性和差异性相对识别的ISODATA算法,对兰州——古浪地区的潜在震源进行了识别,给出了该地区的潜在震源区及其震级上限,为潜在震源区的综合判定提供了可靠的科学依据,使得潜在震源区的综合判定更为合理。
Determination of the potential source area is the base of the seismic risk analysis, the accuracy of the potential source directly effects that the results of the seismic risk analysis are right or not; in this paper, the potential source is identified by using the ISODATA method of the parallelism and difference of multidimensional actual measurement data, by identified the potential source in Lanzhou—Gulang area, the paper gives out the potential. source regions and the magnitude upthreshold, the reliable scientific accordance is supplied to comprehensively identify the potential source regions ,and the accordance makes it more reasonable to comprehensive identification.
