江苏及近海地区构造环境剪应力场的跟踪分析
|
摘要
利用江苏数字地震台网近两年记录的 85个中、小地震数字资料 ,调整了计算参数 ,继续对我省及邻近地区的环境剪应力场作了追踪计算。得出我省及邻区、近海地区几个应力值相对较高的需要注意的地区。
The follow-up calculation of the ambient shear stress field in our province and its neighbouring areas has been continued by the authors using the digital data of 85 moderate and small earthquakes recorded by the Jiangsu Digital Seismological Network in the recent two years. In the calculation, the calculation parameters have been revised on the basis of the recent seismic data. Some areas with relatively high stress values are obtained in Jiangsu Province as well as its neighbouring and offshore regions. More attention should be paid to these areas.
