摘要
本文用下关地震台数字地震仪的主震加速度记录,结合澜沧——耿马地震的宏观考察资料,以波谱法为基础,分别计算了两个主震的运动学、静力学和动力学参数各18个。用以从微观地震学角度描述澜沧——耿马地震的两个主震。通过所求参数的分析对比,认为是澜沧主震触发了耿马主震。
In this paper, the kinematic, static and dynamic parameters of the 1988 Lancang-Gengma mainshocks (18 for each) have been figured out, respectively, based on the wave spectrum method, with the mainshock acceleration recordings from Xiaguan digital station in combination with the macroscopic data. The obtained parameters arc used to interpret the two mainshocks from a point of microscopic seismology. From the analysis and comparison of those parameters, it is held that the Lancang mainshock triggered the Gengma mainshock.
