【摘要】 本文利用我国西南地区地震台记录的一次卡罗林岛地震和一次西里比斯岛地震的瑞利波,进行相位对比,用三台方法计算了各地区瑞利波的相速度。将观测的相速度与理论曲线(采用Press模型)比较,得到各地区的地壳厚度。更多还原

【Abstract】 In this paper, by using the Rayleigh waves recorded at the seismic stations in Southwest China from an earthquake occurred in Caroline and another earthquake in Celebes, a comparison of the phases is made and the phase velocities of Rayleigh waves in different regions are calculated by tripartite seismic station method. Thus, the thicknesses of the crust in different regions are determined on the comparison between the observed phase velocities and theoretical dispersion (F. Press Model adopted).更多还原
