摘要:
新丰江地区近年来有感地震频发,为了震后应急的需要,文中统计了1980年以来该区域M≥3地震后序列的特征。得到以下结论:该区域40次M≥3地震后30天内仅1次发生比主震更大的地震,其余震的衰减时长相比K-K法给出的时间窗长要短很多。按照余震衰减的大森公式,新丰江地区p值偏高。统计得到的这些规律以及拟合的曲线可以为我们在震后快速的对后续余震特征做出初步判断提供依据。
Abstract:
In recent years, there have been frequent felt earthquakes in Xinfengjiang area. In order to meet the needs of post-earthquake emergency response,this paper analyzes the characteristics of post-earthquake sequences of earthquakes with M≥3 in this area since 1980. The conclusions are as follows:only one earthquake larger than the mainshock occurred within 30 days after 40 earthquakes with M≥3 in this area, and the attenuation time of aftershocks is much shorter than the time window given by the K-K method. According to the Omori formula of aftershock attenuation,the p value in Xinfengjiang area is high. These laws obtained by statistics and fitted curves can provide a basis for rapid preliminary judgment of the characteristics of aftershocks sequence after the earthquake
