摘要
分析处理甘肃数字化地震台网记录到的1999年11月至2000年6月的68个地震,给出了甘肃景泰2000年6月6日MS5.9地震前后小地震的视应力变化情况,得到该区的视应力水平,并讨论了主震前后的视应力演化特征以及视应力与震级的关系。
A series of earthquakes (Jingtai M_S 5.9 Earthquake series, there are totally 68 events), recorded by Digital Seismic Network in Gansu Province, are selected to calculate the apparent stress in this region. The authors give the time distribution of apparent stress. Furthermore, the average value of apparent stress is got, which is in accordance with the result got from Wu Zhongliang. The features of apparent stress change before and after the main shock are discussed. At the end, the relation between apparent stress and magnitude is obtained.
