摘要
本文采用了频度衰减系数及余震等待时间两种方法,对广东及邻区近年来发生的较大地震进行了类型判断及震后趋势判断。 在应用频度衰减系数的20个震例中,基本符合实际及符合较好的有17个,占总数85％。 余震等待时间方面,地震系列的余震等待时间的对数与发生时间的对数之间的线性关系较好的震例有:1605年琼山7.5级地震的强余震系列,1962年河源6.1级地震的余震系列、1987年江西寻邬5.5级余震系列。
There are 20 earthquakes of applying the frequency attenuation coefficient method in Guangdong Province and its neibourhood. The results of 17 examples tallied with the actual situation, and these examples' magnitude are comparatively bigger.
There are 3 aftershock series examples ( 1605 Qiongshan , M7.5 earthquake, 1962 Xinfengjiang M6.1 earthqake, 1987 Xunwu M5.5 earthquake ), of which their logarithic values between waiting time and occurring time have good relations in linear.
