摘要
研究了山西地震带近年来数次中强地震前断层位移测量资料显示的异常变化,从背景异常、中期趋势异常和短临异常的不同角度讨论了震前地壳形变特征及应力场变化情况,得出了形变预报指标,并就有关问题进行了讨论。
The paper analyzed the anomaly change showed by the fault displacement measurement data before the moderate and strong earthquakes in Shanxi seismic zone for recent years,discussed the crustal deformationcharacteristics and the stress field change before earthquakes at a different angle of the background anomaly,the medium-term trend anomaly and the short-impending anomaly,obtained the prediction index of the defor-mation and discussed the relative problems.
