Abstract:The comprehensive characteristics of geomagnetic anomalies before the Jinghe M5.4 earthquake on October 16, 2018 were obtained and analyzed using a series of geomagnetic methods such as the geomagnetic daily value spatial correlation, geomagnetic load-unload response ratio, spatial correlation of daily variation of the geomagnetic vertical component, and geomagnetic low-point displacement. These methods showed that there were middle and short-term anomalies before the earthquake. Additionally, the results showed the following aspects. (1) Before the earthquake, multiple anomalies existed, which enhanced the credibility of the methods. (2) The anomalies considerably increased closer to when the earthquake erupted demonstrating that seismogenic probability increased in this area. (3) Compared with a single method, a comprehensive analysis method to identify earthquake locations, can reduce the time scale of prediction. (4) Anomalies in the spatial correlation of the daily variation of the geomagnetic vertical component mainly appeared in the northern Tianshan area before the earthquake. The comprehensive anomalies observed in the Jinghe earthquake illustrated that geomagnetic analysis methods had a certain forecast effectiveness in short-term earthquake prediction.
