摘要
利用山西省及部分邻区近几年的洞体形变观测资料,分析了在几次中强地震前观测数据的分量均值、倾斜矢量、潮汐因子变化等不同指标的异常特征,找出了区域地震前倾斜的共性异常特征和个体异常特征,并与数字观测资料进行了对比研究,指出了数字观测资料在今后地震预报中的应用前景。
Based on observation data of cavity deformation in Shanxi province and its partial adjacent regions recent years, the anomaly characteristics of different indexes such as average value of components, inclining vector and change of tide factor of observation data before several moderate earthquakes are analyzed. Common anomaly characteristic and individual anomaly characteristic of crustal tilt before regional earthquakes are found. Comparison with digital observation data is carried out and the application prospect of digital data in coming earthquake prediction is also pointed out.
