Abstract：This paper introduced the abnormal feature of magnetic declination since 2008 at Maiji Area of Tianshui City before several strong earthquakes in the western region of China.If data is stable,easily identify anomaly,the test items of earthquake short-term monitoring can play a certain role.It is considered that the time of anomaly,the magnitude of the anomaly,the magnitude of the magnitude is larger,and the distance from the epicenter is also relatively close;Otherwise,the magnitude is smaller or the distance of the epicenter is far away.Combining the dynamic anomalies of groundwater change,this paper proved theanomaly of magnetic declination at Maiji Area of Tianshui City,and discussed the understanding during the research process.
