2013年四川芦山Ms7.0地震余震序列重新定位
Relocation of aftershocks of Lushan Ms 7.0 earthquake in Sichuan Province, 2013
摘要
Abstract
Based on the records from 35 research stations and Sichuan network,the aflershocks of Lushan Ms 7.0 earthquake between June 25,2013 and December 31,2014 are relocated,using the Hypo2000+HypoDD combined method.After relocated,the average error of EW,NS and UD are 0.141 km,0.143 km,and 0.147 km,respectively.The average travel time residual is 0.066 s.Most aftershocks occurred at depth of 8-18 km.The results suggest that the aftershocks concentrate between Dayi-Mingshan and Shuangshi-Dachuan fault,forming a southwest-trending belt with about 40 km long.关键词
