地倾斜异常图像与地震预测
Anomaly images of crustal tilte and earthquake prediction
【摘要】 系统分析了1988~1998年期间新疆4个台站、5套地倾斜仪记录到的异常图像,发现与周围的4级以上及强远震有较好的对应关系。在对图像特征、典型震例研究的基础上,归纳了异常图像的识别标志、与地震关系的定性指标;对异常图像的可能机制作了初步讨论,认为可能是岩石临破裂前的裂隙扩展、断层预滑的直接记录;地倾斜异常图像的研究对地震的短临预报具有参考价值。
【Abstract】 The anomaly images from 5 sets data of crust titles from 1988 to 1998 are analyzed systematically.We find that the anomaly images are relative to the earthquakes with magnitude greater than 4 occurred around the seismic stations and think that these anomaly images result from the rift developing before the crust rock breaks or fore-split.So we made a primary discussion about the possible mechanism of the anomaly images and our work is of reference value for the earthquake prediction.
