| 摘 要： | 2007—2009年福建及邻近地区共发生4级以上地震10次。 这些频繁发生的中等强度地震, 给当地居民的生活带来了不小的影响, 因而有必要加强对这些地震的分析研究。 本文利用BSL开发的矩张量反演程序TDMT_INVC, 使用福建数字地震台网宽频带台站地震波形记录, 对2007—2009年福建地区发生的4次ML>4.2地震的震源机制解进行反演, 并对反演得到的震源机制解进行分析; 在反演过程中, 利用波形拟合方法确定这4次地震的震源深度。 |
| 关 键 词： | 中等强度地震 矩张量反演 区域地震台网 宽频带台站 |

| Abstract: | Ten earthquakes (ML≥4) occurred in Fujian and its adjacent areas from 2007 to 2009. These frequently occurred moderate earthquakes actually affected the local people's life. It is necessary to strengthen the study of the earthquakes. In this paper, focal mechanism solutions of four earthquakes (ML>4.2) have been calculated by using broadband digital data of Fujian earthquake network and the seismic moment tensor inverse software TDMT_INVC developed by Douglas Dreger of the Berkeley Seismological Laboratory. The results of focal mechanism solutions are analyzed. The focal depths are determined in the inversion. |
| Keywords: | Moderate earthquake Moment tensor inverse regional broadband seismic network Fujian region |
