摘要
分析2011-01～2013-11福建数字台网记录到的73个福建仙游地震,给出仙游2013-09-04 ML5.0地震前后小地震视应力变化情况,得到该区的视应力水平,并讨论主震前后的视应力演化特征以及视应力与震级和深度的关系。
A series of earthquakes （the Xianyou ME5. 0 Earthquakes series; totally 73 events）, recorded by digital seismic network of Fujian province, are selected to calculate the apparent stress in this region. The pa- per gives the time distribution and the area of the apparent stress level. The features of apparent stress change before and after the main shock are discussed. Finally, the relation between apparent stress, magnitude and hypoeenter depth is obtained.
