The VAN method enables estimation of the epicenter, magnitude and occurrence time of an impending earthquake by observing transient changes of the electric field of the Earth termed seismic electric signals （SES）. Here, we present a few examples of SES observed in various earthquake prone areas worldwide.展开更多
