In this work a review is made of the various preseismic electric signals thathave been observed before large EQs in Greece during the period of 1999 to2012. The observed preseismic electric signals comply quite well with thetheoretical ones that are expected to be generated by a large scalepiezoelectric mechanism been activatsd at the focal area due to its excessstress-load. Preseismic electric signals of the total piezoelectric field, itsfirst time derivative, its oscillation due to M1 and K1 tidal components havebeen observed by single monitoring sites during the actual 1999 to 2012experiment in Greece. Moreover, the "strange attractor like" electricpreseismic signal was detected by the simultaneously use of two distantmonitoring sites. It is demonstrated that the preseismic electric signals cannot only determine quite accurately a very short time window for the EQoccurrence and its epicentral location but the latter can be achieved withoutany prior knowledge of the geological, tectonic setting or past seismic historyof the seismogenic area. The predicted pending EQ is treated as a singleisolated destructive nature event which sends clear warning signals well beforeits occurrence. Real examples are presented from the Greek territory.  Key words: piezoelectricity, electric preseismic signals, strange attractorlike, earthquake prediction.

Preseismic electric signals generated by critical stress loading of the  lithosphere. A review of the type of signals obtained from a long lasted  (1999 to 2012) experiment conducted in Greece
