| 摘 要： | 地震发生后，盲场快速评估阶段生成的地震影响场对极震区的判定和应急救援的实施起着重要的作用。震后依据地震震级、震中所在地区的地震烈度衰减关系和活动断裂分布情况可快速绘制第1时段地震影响场，然后综合考虑此次地震震源的特性，充分利用余震序列、震源机制解等结果可动态修正影响场。本文基于开源软件实现地震影响场的自动生成，并依据余震序列、震源机制解等结果，实现动态修正地震影响场，为震后灾情评估和多时段应急图件产出打下基础。

| Abstract: | The seismic influence field generated in the off-site rapid assessment plays an important role in the determination of extreme disaster areas and the implementation of emergency rescue. The seismic influence filed would be generated based on the magnitude, the attenuation relationship, and the active fault distribution at the epicenter location in the first period after the earthquake. And then, considering the characteristics of the epicenter, and utilizing the aftershocks and the focal mechanism solutions, the seismic influence field would be revised dynamically. This paper describes the automatic generation of seismic influence field with open source software, and the dynamic revision based on aftershocks distribution and focal mechanism solution. The result might lay the foundation for disaster assessment and multi-period output of emergency maps. |
