摘要
本文使用沧澜—耿马地震主震后在震区建立的数字地震仪记录,用波谱法测算澜沧—耿马余震的震源动力学参数。就这些参数的统计特征,对该双主震型两主震区的地下介质不同状态予以讨论。
Using the digital data, recorded in the seismic area after mainshocks, the focal dynamic parameters of Lancang-Gengma aftershocks have been calculated by the wave spectrum method. The different medium states beneath the two mainshock areas of this earthquake sequence have been discussed from a point of the statistical features of these parameters.
