陕西中南部的视应力场研究

STUDY ON APPARENT STRESS IN THE MIDDLE AND SOUTHERN PARTS OF SHAANXI PROVINCE

摘要:

利用西安数字地震台网的宽频带数字地震记录,计算了陕西中、南部地震的视应力水平,并讨论了泾阳5.2级地震前后地震视应力的时间变化特征及视应力与震级的关系。

Abstract:

Using the digital seismic data recorded by xi'an digital seismic network, the average value of apparent stresses of earthquakes in the middle and southern parts of Shaanxi province are calculated.The variation of the apparent stress before and after Jingyang M_L5.2 earthquake and the relationship between apparent stress and magnitudes are then discussed.
