| 摘 要： | 利用新疆和田地震台阵数据,应用宽频F-K分析方法,结合新疆数字地震台网部分台站数据,通过震相到时、方位角和慢度的线形化反演地震定位方法对2008年3月21日新疆于田7.3级地震及2008年3月21日~2008年8月31日ML≥4.0的余震序列中119次地震进行重新定位,重新定位结果与新疆区域地震台网定位结果有明显差异。重新定位结果表明,于田7.3级地震序列呈近NS向条带分布,与野外考察发现地表破裂带基本一致。研究结果表明,利用地震台阵结合部分区域地震台网数据,可以对台网相对稀疏地区的地震进行较为精确的定位,可为基础研究和震情趋势判定提供基础资料。

| Abstract: | Using the data recorded by Xinjiang Hetian Seismic Array and the data recorded by a few stations of Xinjiang digital seismic network,using liner inverse seismic location method that use seismic phase arrival time,azimuth and slowness to relocate 119 earthquakes of Yutian MS7.3 and its aftershock with ML≥4.0 from Mar.21 to Aug.31,2008.There is obvious difference between the relocating result and the result of Xinjiang catalog.The relocating result shows,distribution of the seismic sequence of Yutian MS7.3 Earthquake is close to NS direction,it is consistent with the survey surface rupture result of field work.This shows that combing the data recorded by Xinjiang Hetian Seismic Array and a few stations of Xinjiang digital seismic network to locate the earthquakes where the seismic network is sparse,it will make the location precision advance,and it can give basic data for fundamental research and earthquake forecast. |
