本文研究了地震时间、震级的相互关系,说明:一、时间轴上相邻地震的视相互作用服从韦布尔分布,其二阶以内矩的比值ν表示地震的发生方式(周期性、随机性、续发性)。茅山地区的ν值过程表明:中强震前的小震具有续发性;1974年和1979年溧阳的两次中强地震可视为同一地震序列。二、震级变量的相互作用服从古登堡—里克特公式,一般由b值曲线反映。茅山地区的b值过程表明:溧阳两次中强震前均出现低b值过程。
In this paper, the relationship between seismic time and magnitude is studied. The results show that: (1) The apparent interaction between adjacent earthquakes on the time axis obeys Weibull distribution, and the second-order moment ratio ν indicates the occurrence of the earthquake (cyclicality, randomness, Continued sex). The ν value process in Maoshan area shows that the small earthquakes before the moderate-strong earthquakes have the possibility of recurrence. The two moderate earthquakes in 1974 and 1979 can be regarded as the same earthquake sequence. Second, the interaction of magnitude variables subject to Gutenberg - Ricote formula, generally reflected by the b-value curve. The b value process in Maoshan area shows that there are low b values before the middle strong earthquakes in Liyang.
