Before the earthquake,the water level of Huanghua well in Hebei Province with the epicenter distance of 468km had a significant short-term decreasing anomaly. The abnormal process and Yingkou earthquake sequence of smaller magnitude make a complete comparison. The paper analyzes the anomaly phenomenon in terms of tectonic structure,dynamics environment and focal mechanism. The result shows that there is a certain correlation between tectonic activity and the anomaly,which can be taken as a significant short-term anomaly in far-field. %R %U http://zgdz.eq-j.cn/zgdz/home %1 JIS Version 3.0.0
