Pre-Seismic Geomagnetic Anomaly Using Second Data and Its Significance in Earthquake Short-Term Prediction
Sun Xulong
Abstract：According to the result of geomagnetic data,great abnormal magnetic phenomenon occurring repeatedly before some significant earthquakes were found.This kind of phenomenon occurs about from over forty to a hundred days before.This pre-seismic geomagnetic anomaly lasts long as the magnitude increases.The nature of geomagnetic data before earthquakes has something to do with earthquake prediction and may be applied to precaution against earthquake disasters.
