摘要

At 8:02 a.m. Beijing time on April 20, 2013, an Ms 7.0 earthquake shook the city of Ya'an, China. Until 24:00:00 on 20 July 2013, a total of 339 strong-motion records from 113 free-field stations, 21 records from 1 strong-motion structure array and 1123 groups of aftershock records have been collected, processed and analyzed preliminarily by the China Strong Motion Network Center (CSMNC) in this paper. There are more than 26 stations located within Longmenshan fault zone and all peak ground acceleration (PGA) of records is larger than 50gal. The PGA of Baoxingdiban station reaches 1005.4 gal after zero-line initialization, which firstly breaks through 1g in the mainland of China. Based on the mainshock records, shakemaps of those PGAs are plotted and attenuation relationships of PGAs are presented in this article.
