摘要
通过对离石中心地震台洞体形变近6年观测资料中典型异常形态及与其相关地震的对应关系进行分析,结果表明,异常形态主要表现为短期趋势转折,突跳、毛刺、加粗等的数据波动,固体潮畸变伴掉格,且大多数异常是3种形态的组合;多数异常在震前发生,震后迅速恢复,固体潮分钟值曲线上有同步变化;水平摆和伸缩仪对应国内外6级以上的地震出现不同程度的异常反映,水管仪表现不明显。
Typical anomalous patterns of cave deformation observed at Lishi seismologic station in recent 6 years and their corresponding relations with related earthquakes are analyzed. The results show that the anomalies are mainly characterized by short-term trend turning, data fluctuation of sudden jump, burr and coarsening, distortions of solid tide, and most of the anomalies are combinations of three forms. Most of the anomalies occur before earthquakes, and recover rapidly after earthquakes, and the minute curve of solid tide has synchronous changes. Horizontal pendulum and telescoping instrument have different degrees of abnormal reflection corresponding to earthquakes with magnitude 6 or more at home and abroad, but water pipe meters are not obvious.
