摘要
Abstract
On the basis of 10935 broadband velocity records of 135 earthquakes (ML3.0-6.4 and epicentral distance of 26-623 km) occurred from May 12 to June 10 in 2008, which are collected from 27 bedrock stations included in Sichuan Earthquake Monitoring Network, the corresponding acceleration records are obtained by a real-time simulation method. Then by regression analysis on the data, the relation between the peak ground acceleration and velocity attenuation of small and moderate bedrock earthquakes occurred in Sichuan region is acquired. And the relation is verified by a A/4.8 earthquake took place recently in Wenchuan. Finally, the attenuation relations, which are coincident to the geological conditions in Sichuan region, are proposed by studying the records from Sichuan earthquake network.关键词
