摘要
针对双王井2021年4月10日出现的大幅度水位下降异常进行了现场核实,对仪器的运行情况、网络连通情况、供电情况、台站周围环境情况进行了初步的核实,并进行水位实地校测,对比了同时段、同一观测点其他测项和周邻台站数据资料。经过分析与探讨判定此次水位下降异常是由于周边基建大量抽水引起的水位异常变化,而非地震前兆异常。
In response to the significant water level drop anomaly in Shuangwang well on April 10,2021,we verified the operation of the instruments, network connectivity, power supply, and the environment around the station.Then field calibration of the water level, compared the data onto other at the same measure point and the vicinity of the place at the same time period. After analysis and discussion, it was determined that the water level drop anomaly was caused by a large amount of water pumping in the surrounding environment, which not belong to precursor anomaly of earthquakes.
