摘要
双阳地震台DSQ型水管倾斜仪NS分量自2019年10月以来出现加速S倾打破年变形态的异常变化情况。为此对该测项仪器观测状态、观测环境变化、观测台站附近干扰等因素进行科学合理的分析研究,综合分析认为双阳台水管倾斜仪NS分量S倾加速变化为前兆异常。
Since October 2019,the NS component of the DSQ water-tube tilt meter at Shuangyang Seismic Station has been accelerating the southward inclination to break the annual variation.For this reason,scientific and reasonable analysis and research on the observation status of the measuring instrument,rainfall data,interference near the observation station and other factors have been carried out.After omprehensive analysis,it shows that the acceleration change of the NS component of the water-tube tilt meter is a precursor anomaly.
