震磁效应即是由于地震引起的地磁场的可能的物理效应。对震磁效应的观测和研究虽已有百余年的历史,但对其规律性远没有掌握,有关震磁效应的机制虽有矛盾之处,但也有一定的理论和实践依据,并且积累了不少震例资料,因此,在地震预报和研究中,它吸引了许 The seismic magnetic effect is the possible physical effect of the geomagnetic field caused by the earthquake. Though there are more than one hundred years of observation and research on the seismic magnetic effect, its regularity is far from being mastered. Although there are contradictions in the mechanism of the seismic magnetic effect, there are also some theoretical and practical bases for the observation and study of the seismic magnetic effect A lot of earthquake data, so in the earthquake prediction and research, it attracted Xu
