| 摘 要： | 利用1987年１月～1998年12月的NEIC宽频带地震辐射能量目录和哈佛CMT目录，给出了中国大陆地震的视应力分布．由于资料所限，主要结果是针对西部的结果．所得结果表明，中国大陆地震的视应力平均为0.8MPa．青藏高原东缘的视应力最高为2.6 MPa，平均水平高于其邻近地区一倍以上．视应力分布与20世纪的累积地震能量分布具有一定的相关性．

| Abstract: | Distribution of apparent stress in Chinese mainland and its surrounding regions was presented using the NEIC broadband radiated energy catalogue and the Harvard CMT catalogue from January 1987 to December 1998. Due to the limitation on the number of samples, reliable results are only for the western China. It is observed that the average apparent stress in Chinese mainland is 0.8 MPa; The maximum apparent stress to the east of the Tibetan plateau is 2.6 MPa; And the average apparent stress in the north-south seismic belt is more than one time higher than its adjacent regions. Distribution pattern of apparent stress seems to have a large-scale correlation with the cumulative energy release level in the 20th century. |
