Relationship between Rainfall and Water Level in Deep Wells: A Case Study of Chenjiang Well and Jianshui Well in South of Yunnan Province

摘要: 2015年1月9日，云南地区出现大幅度水位同步转折上升现象，而地下流体群体异常的聚集区可能是未来强震的孕育区，及时排除环境等干扰因素，对确定地震危险区很有帮助。本文选取澄江井和建水井的水位观测数据，分析降雨量与水位变化的关系，认为滇南地区的水位年变化与雨季降雨量之间有较好的线性关系。本文对澄江井和建水井2012-2014年的水位异常信息进行提取，对其映震情况进行了总结，研究表明滇南地区降雨量对水位引起的异常，主要表现在变化幅度和变化时间等方面。此次出现的水位同步转折上升现象多为降雨干扰影响。Abstract: Water levels were raised synchronously and sharply by a large margin in the Yunnan area since January 9, 2015. The related area with systematic anomaly of underground fluid may be the signal for strong earthquake preparation. However, such anomaly could also be caused by non-earthquake related factors. In this paper, we selected the observation data of Chenjiang well and Jianshui well, to study the relationship between rainfall and the variable quantity of water level. We found that there exists a clear linear relationship between rainfall and the variation of water level in south of the Yunnan area. Then, we extracted the abnormal information of water level of Chenjiang well and Jianshui well from 2012 to 2014, and analyzed the earthquake reflecting features. Finally, we concluded that abnormal changes of water level are mainly caused by rainfall variation.
