目前,地震活动性的研究已开始由单一指标,定性描述向定量计算的方向发展。谷继成等〔1〕最近提出的地震活动度的概念,是将地震频度,地震能量(平均震级),最大震级和空间分布特征等各因子综合考虑,引用加权海明相对距离的概念定义综合表述地震活动性特征的量,它不仅包含了时、空、强各因子,而且将地震活动性的研究推向了定量化。本文引用读方法做了聊考断裂周围地区的工作,并结合研究断裂带的具体情况,在其计算模型的基础上,新增加了密集条带因子 P,使读计算模型更加符合本区域的特殊情况。在研究了 S(T)(地震活动度随时间的变化)以后,我们又引用这一概念对聊考断裂做了空间扫描,进一步分析了 S(s)(地震活动度随空间的变化)在断裂每一段上的变化情况,从 S 的时空变化情况可知:聊考断裂带目前正处于一个较强的地震活动期,活动的重要范围集中在断裂中南段的菏泽—东明一带。
At present, the study of seismicity has begun to develop from a single indicator, qualitative description to quantitative calculation. Gu Ji-Cheng et al [1] recently proposed the concept of seismicity is the seismic frequency, seismic energy (average magnitude), the maximum magnitude and spatial distribution of various factors such as comprehensive consideration, the concept of weighted Hamming relative distance definition of a comprehensive statement The amount of seismicity features not only includes time, space, and strong factors, but also researches the seismicity activity to quantitative. This paper refers to the reading method to chat about the work of the area around the fault, and combined with the study of the specific conditions of the fault zone, on the basis of its calculation model, a new dense banding factor P is added to make the read calculation model more in line with the special Happening. After studying S (T) (the change of seismicity with time), we also make a spatial scanning of the Tiao fault by reference to this concept. We further analyze that S (s) (the change of seismic activity with space) According to the temporal and spatial variation of S, the Chatou fault zone is currently in a strong period of seismic activity, and the important range of activities is concentrated in the Heze-Dongming area of the middle and southern section of the fault.
