摘要
利用福建省地震局在顺昌ML 4.9地震后布设的流动台网记录到的顺昌地震余震波形资料,应用SAM剪切波分裂分析方法,计算并得到顺昌余震的快波偏振方向和慢波时间延迟。结果表明,顺昌地区的快波偏振方向为北东向,与顺昌地区断裂带走向一致。
Using the seismic data recorded by near source digital seismic network installed by Earth- quake Administration of Fujian Province after the Shunchang ML 4. 9 earthquake, we measured the shear-wave splitting parameters of the afte/shock recordings by the systematic analysis method （SAM） of shear-wave splitting. The results show that the fast shear-wave polarization directions is NE direction, consistent with the strike of the faults in Shunchang region.
