| 摘 要： | 利用Hypocenter和Hypo2000地震定位法对2008年8月30日至2008 年11月30日四川攀枝花-会理发生的地震序列进行精确定位,就两种定位法的震中分布、深度剖面、地震震中平面距离差、震源深度做了对比分析.结果表明:Hypocenter地震定位法与Hypo2000地震定位法定位结果比较吻合,定位效果较好.从Hypo2000方法给出的定位结果可以看出震中集中和收敛更清晰地勾画出了地震断层的空间走向.地震序列震中呈近南北方向分布, 总长度约37 km..地震序列主要集中在元谋断裂带,震源深度的优势分布在5～15 km之间, 平均震源深度为9.7 km.

| Abstract: | We relocate earthquake swarms that occurred in Panzhihua and Huili,Sichuan,during the period 30 August to 30 November using Hypocenter method and Hypo2000 method respectively.A comparison of relocated seismicity using the two different relocation techniques,the relocated earthquake patterns such as epicenter distribution,focal depth cross-section,epicenter migration and so on,have similar results.The earthquakes relocated by Hypo2000 method have a sharper pattern,which is more clearly delineate a fault trac... |
