【摘要】 利用1900～2005年的中强震地震资料计算了中国大陆地震的平均视应力。中国大陆平均视应力为0.67MPa,略高于全球平均水平,中国东部平均视应力为0.32MPa,西部为0.97MPa。研究表明:利用地震震级计算的中国大陆地震视应力大小与利用数字地震波资料测定结果相差不大,其空间分布基本一致。更多还原

【Abstract】 The average seismic apparent stress and its distribution in Chinese mainland are presented by use of data of medium-strong earthquake from 1900 to 2005.The stress is 0.67 MPa, more than the global level a little and 0.32 MPa in eastern China,0.97 MPa in western China. It is turns out that the average seismic apparent stress calculated with seismic magnitude in Chinese mainland is similar to that calculated with digital seismic wave data and the distribution is coincident with each other.更多还原
