摘要
依据最大熵原理求解出地震震级和地震间隔时间的最可几分布为威布尔(Weibull)分布 .以甘肃天祝地区为例 ,应用极值分布模型、对数正态分布模型和威布尔分布模型以及K S检验和直方图检验 2种方法 ,分别对该地区实际地震数据进行检验 .
According to the theory of greatest entropy, it is found that the most probable distribution of magnitude and interval time of earthquake are Weibull distribution. Using of K S test and histogram test, actual seismic date about magnitude and interval time of earthquake of Tianzhu region, Gansu province from 1970 to 1990 are inspected with three models. The result obtained is identical with that by the theory.
