摘要
分析了2004年12月以来全球7级以上强震和中国5级以上地震的同震效应特征,当震中距较小时,同震应变阶似单纯的阶跃;而当震中距较大时,阶跃具有脉冲的形式,曲线有一个往返变化。初步总结了不同震中距时,竖直摆倾斜记录地震波动的能力。
The characteristics of coseismal effect about strong motion of above seven magnitude in global and above five magnitude in China since Dec of 2004 were analyzed in this paper. When epicentral distance is little, the coseismal strain step is similar to pure phase step. While the epicentral distance is larger, the coseismal strain step is similar to pulse changed out and back. The ability of recorded seismogram about tilting vertical pendulum was generalized preliminarily with different epicentral distance.
