摘要
对辽宁岫岩一号井"九五"和"十五"水温数据进行了分析和总结。结合省内地震活动后前兆异常,对2013年9月水温出现加速升高,幅度达到7‰,之后处于高值波动状态进行分析。结果认为岫岩"一号井"水温虽然日动态稳定性较差,对小震的映震效果不明显,基于2012—2016年营口—盖州及海城—岫岩地区地震活动性有明显加强,重力场异常目前尚未结束,省内前兆异常主要集中在朝阳-北票断裂和下辽河盆地附近,2013年9月以来出现的中期异常呈北西向带状分布(包括岫岩水温),提出岫岩水温高值情况应该继续加强跟踪研判。
In this paper,the water temperature data of the Xiuyan No.1 well in the Liaoning Province during the 9th and 10th five-year plan were analyzed and summarized.In addition to earthquake activity and precursory anomalies in the Liaoning Province,we focused on the increase of digital water temperature in the well since September,2013.The results show that,during the 10th five-year plan,the daily dynamic stability of water temperature in the Xiuyan No.1 well is rather poor,and not correlated well with the small earthquakes.The mid-term anomaly of water temperature since September,2013 was distributed northwestwards in the form of a belt;thus,it was evident that we should continue to strengthen tracking and research on the high value of the Xiuyan water temperature.
