Abstract:

On the basis of seismogeology, geophysics and seismicity, the improved Cora-3 and Hamming method are used to delineate the potential seismic sources with magnitude of 6,6.5 and more than 7 in Liaoning Province and its adjacent area, the results deduced from two methods are consistent each other. Through the tests of k value, deleting objects and characters it is enough to prove the achieved result reliable and convincing. This work may bridge the gap in regrad to the field of the pattern recognition which has been carried out in Liaoning region and provide a basis for determing the potential seismic sources in Liaoning Province and its adjacent area.

Key words: Pattern recognition, Potential seismic sources, Objects, Character, Threshold, Liaoning

摘要：

采用Cora-3修改方法和Hamming方法对辽宁及其邻区的地震地质、地球物理场和地震活动性特征进行研究,划分了6级、6.5级和7级以上潜在震源区,两种方法所得结果基本一致。经k值试验、删除对象试验和删除特征试验,均表明结果比较稳定可靠。这一成果弥补了辽宁地区这方面工作的不足,并为确定辽宁及其邻区的潜在震源区提供了依据。
