| 摘 要： | 对多次强震的地震视应力进行了计算，将各次强震的地震视应力的高低与强震发生后的后续地震的强度进行联系，探索它们之间的关系，进而提出将地震视应力用于强震震后趋势预测的可能性。对多次强震的地震视应力与其后续地震强度的关系的分析结果表明，低视应力的强震的后续地震的强度一般较低，即低视应力的强震发生后，震区发生较强的后续地震的可能性较小。

| Abstract: | The authors calculate the apparent stresses of several strong earthquakes, relate the intensity of apparent stresses of the strong earthquakes with the magnitude of the successive earthquakes following the strong earthquakes to seek for the relationship between them, and point out the possibility of applying apparent stresses to seismic tendency prediction after strong earthquakes. The analyses of the relationships between apparent stresses of several strong earthquakes and the magnitude of the successive earthquakes show that magnitude of successive earthquakes after strong earthquakes with low apparent stresses is generally relatively small, that is, after the occurrence of strong earthquakes with low apparent stresses, there is little possibility that successive earthquakes with relatively high magnitude would take place in earthquake areas. |
