摘要
2013年7月4日永安地震台观测井进行数字化改造,安装了福建省首台SWY-II型数字式水位仪,并且同步安装了SZW-1AV2004数字式温度计和WYY-1型气温、气压、降水量综合测量仪。以2014、2015、2016三年数字化观测资料为研究对象,对水位资料的年、月、日动态特征及主要干扰因素等进行分析,研究数字化观测水位在地震前兆监测中的效能情况。结果表明:水位数字化观测资料连续可靠,对大地震有明显的同震效应,地壳应力-应变响应灵敏度高。观测资料年变规律明显,有望在破坏性地震的中期或中短期前兆监测中发挥一定的效能。
Based on the water level data of the well during 2014 and 2016, the paper analyzed the annual,monthly and daily dynamic characteristics of water level data and main disturbance factors, and studied the efficiency of the digital observation well water level in the earthquake precursor monitoring. The results show that the water level digital observation data is continuous and reliable, significant coseismic effect to large earthquake,and the crust stress-strain response is highly sensitive. The yearly behaviors have some regularity, and can exert its＇ efficiency in the medium term or the short term precursory monitoring.
