The comprehensive character of geomagnetic anomaly in the Jinghe M_S6.6 earthquake on August 9, 2017 has been summed up and analysed with geomagnetic Z component daily ratio, geomagnetic load-unload response ratio, harmonic wave amplitude ratio, geomagnetic low-point time, morphological analysis methods. It is found that the geomagnetic showed obvious middle-and short-term anomalies.
