| 摘 要： | 介绍了2009年姚安Ms6.0地震强震动应急流动观测台站的布设、记录获取及初步处理结果等情况,并对此次地震余震的高加速度峰值、低地震烈度等有关问题予以讨论,结果认为:场地条件对地面地震动峰值影响较大；高地震动峰值的相对持时短是此次4.7级余震震害轻的主要原因.

| Abstract: | Firstly,we introduce the emergency actions we took against the Yao'an MS6.0 earthquake on July 9,2009,such as the deployment of the mobile stations of strong motion,the capture and process of the strong motion recordings of the Yao'an aftershocks,etc.Then,through discussing the phenomenon of the highpeak acceleration and low intensity of the MS4.7 aftershock,we find that the site condition has a significant effect on the peak of ground motion,and it is the short relative-duration of the peak-value of the af... |
