【摘要】 庐江地震台汤池1号井的水氡测值从2009年4月8开始有小幅趋势性上升,8月4日至8月8日,上升速度加快(8月7日升至11.4 Bq/L),8月19日数值恢复正常。本研究从地震前兆异常落实的角度出发,在仪器运行、观测环境、水文地质、人为因素,仪器标定参数、同一井中其他测项的数据变化、同一地热区其他热水井水样数据的对比等方面进行分析,并结合以往水氡资料的映震实例,初步判定此异常为前兆异常。此项工作对今后异常的判断、识别提供了方法和依据。更多还原

【Abstract】 Since April 8, 2009, the water radon has been rising in the No.1 well of Tangchi Seismic Station.The speed is increasing from 4 to 8 August (It has been 11.4 Bq/L on 7 August).It comes back to common value on August 19th.In terms of anomaly implementation for earthquake precursor, the article focus on the analysis of operation of the instrument, observation environment, hydrology, artificial cause, calibration parameter of instrument, the data changes of the other tests in the same well and the data of other hot well water sample in the same hot water area, and combine living prediction examples of historical data.It comes to an initial conclusion that the anomaly could be precursor anomaly.The research provides the method and the evidence for the anomaly judgment and recognition in the future.更多还原
