摘要

通过对数字石英水平摆倾斜仪最近几年积累数据的分析,发现在大多数中强远震发生前数小时,倾斜仪东西分量观测数据锯齿状异常、固体潮曲线出现畸变并伴有明显的抖动,这对异常识别和地震预测具有一定的参考价值。
        By analyzing the accumulated data of digital quartz horizontal pendulum tiltmeter in recent years,it is found that several hours before the occurrence of most moderate-strong and long-distance earthquakes,the observed data of the east-west component of the tiltmeter are serrated,and the solid tide curve is distorted and accompanied by obvious jitter.These studies have certain reference value for anomaly identification and earthquake prediction.
