Abstract：Based on observation data from the National Geomagnetic Network Center, we study the relationship between the geomagnetic low-point displacement anomaly and earthquakes above 5 magnitude in the mainland of China in the 10 years from 2013 to 2022. The results show good correlation between the geomagnetic low-point displacement anomaly and earthquakes above 5 magnitude. There is high probability of earthquakes with magnitude greater than 5 within 300 km of the anomaly boundary within 2 months after the occurrence of geomagnetic low-point displacement anomaly. The results show that 160 main earthquakes with MS≥5 occurred in mainland China in 2013 to 2022, with an anomaly correspondence rate of 32.4%, the false alarm rate of 67.5%, the false negative rate of 48.1% and the earthquake prediction rate of 55.0%. There is one low-point displacement anomaly before 46 earthquakes, and two or more anomalies before 42 earthquakes. The study also found that superimposing multiple low-point displacement anomaly boundaries before an earthquake on the same base map will form one or more intersection areas, and earthquakes often occur in the intersection area of the low-point displacement boundary. Based on the distribution of active tectonic faults, the occurrence of historical large earthquakes, the potential danger zone of strong earthquakes predicted in the medium and long term and the annual national earthquake danger zone, we further judge the possible earthquake area. This study greatly reduces the range of earthquake location predicted by geomagnetic low point displacement method.
