通河地震台2007年开展SZW-1A数字式水温仪和静水位观测记录,工作较稳定,观测数据可靠性高,观测质量较好,具有一定的年变规律。2015年2月28日-10月15日井水温多次出现突升、突降现象,变化幅度较大,历时较长,且每次变化幅度和周期皆不同;静水位2015年打破年变规律,在往年应该处于上升趋势的时段,水位持续下降。分析认为,通河地震台水温、水位2015年破年变的变化由含水层局部地区发生塑性形变引起。
It has been carried out of SZW-1A digital temperature meter and static water level observation at Tonghe seismic station since 2007. The observation is stable. The observation data is of high reliability and good quality, and shows a regular annual variation. During February 28th to October 15th, 2015, abrupt rise and fall phenomena of water temperature appeared repeatedly. The changes were of great and lasted longer. The amplitude and cycle of each change is different. The change of static water level in 2015 years breaks annual variation pattern in previous years. The water level continuously dropped during the period that it should be in upward trend in previous years. Analysts believe that phenomenon of the changes of water temperature and water level at Tonghe seismic station in 2015 breaking annual variation trend is caused by aquifer local plastic deformation.
