备注

2021年5月22日,青海玛多发生7.4级地震后,5月24日,安徽霍山县佛子岭水库水体出现大面积发白、发浑的宏观异常。通过介绍此次宏观的异常特征、核实过程及水样检测结果,并对水库的水化学参数时空分布特征、气象因素及地震活动等影响的深入分析,认为该宏观异常为地震前兆的可能性小。
After the MS 7.4 earthquake in Maduo, Qinghai On May 22nd, 2021, a large area of macroscopic anomalies of white and muddy water appeared in the water body of Foziling Reservoir in Huoshan County,Anhui Province on May 24th. This paper introduces the macroscopic abnormal characteristics, verification process and detection results of water sample, and analyzes the temporal and spatial distribution characteristics of water chemical parameters, meteorological factors and seismic activities of the reservoir in depth. It is considered that the macro anomaly is unlikely to be an earthquake precursor.
