| 摘 要： | 在现有的日常地震演练过程中,与应急救援密切相关的地震余震信息产品较为缺乏,直接影响发震构造的判断以及影响场修正等关键环节。本文从计算机系统提供的均匀分布随机数出发,运用反函数法模拟生成余震序列,并进行系统检验,证实该方法产生的余震序列满足G-R频次关系。模拟生成的余震震级数据既有助于增强地震应急救援演练的现实性,也有助于丰富地震应急宣传产品,提升地震部门的履职能力。

| Abstract: | Insufficient aftershock information, which is one of the key factors to emergency rescue, directly affects the essential steps such as seismogenic structure determination and influence field correction in the daily exercise against earthquake. In this paper we simulate and generate aftershock sequence by using inverse function method on uniformly distributed random numbers generated by computer system, Then we carry out system examination with the simulation results, and finally prove that the aftershock sequence generated by this method satisfies the magnitude distribution from G-R relation. The simulated aftershock sequence not only helps to enhance the reality of emergency rescue exercise against, but also contributes to enrich promotional products of earthquake emergency response and improves the executing capacity of earthquake departments. |
