摘要
Firstly, the authors 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, the authors 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 aftershock that mainly caused serious damage despite the low intensity.
