The VAN experimental method of short-term earthquake prediction (named after the initials of three Greek physicists, Panayiotis Varotsos, Kessar Alexopoulos, and Konstantine Nomicos) has been used to monitor preseismic electric signals since the 1980s [see Varotsos, 2005]. From observed telluric current signals, called seismic electric signals (SES), the epicentral area, magnitude, and occurrence time of an impending earthquake are estimated. SES are interpreted as having been emitted when the focal region in which the earthquake in question could occur has entered the critical regime (i.e., a stage close to the rupture).
