基于2005年江西九江—瑞昌MS5.7地震序列事件波形及其观测报告,采用双差重定位法、波形互相关法和尾波干涉法,筛选出了同时被范镇台和九江台记录且波形互相关系数≥0.940的两组重复地震对:D1(2005-11-2909:13ML2.0和2005-12-0204:54ML1.9)和D2(2005-12-0223:49ML2.2、2005-12-0616:58ML1.7和2006-03-2406:24ML2.4)。发现MS5.7地震后短期内(2005-11-29—2005-12-02)S波早期尾波波速增加;而MS5.7地震后几个月时间内(2005-12-02—2006-03-24)S波早期尾波波速减小。
- Abstract:
-
Based on the event waveform data and its observation report of the Jiujiang-Ruichang MS5.7 earthquake sequence in Jiangxi in 2005,by using the double-difference method,waveform cross-correlation and coda wave interferometry, two groups of repeated earthquakes(cc≥0.940,recorded by Fanzhen station and Jiujiang station) can be obtained: D1(2005-11-29 09: 13 ML2.0 and 2005-12-02 04: 54 ML1.9)and D2(2005-12-02 23: 49 ML2.2, 2005-12-06 16:58 ML1.7 and 2006-03-24 06:24 ML2.4). It is found that the velocity of early coda wave of S wave increases in the early short period(from 2005-11-29 to 2005-12-02)after the MS5.7 earthquake and decreases within a few months after the MS 5.7 earthquake(2005-12-02-2006-03-24)
