Investigation of the seismicity after the initiation of a Seismic Electric Signal activity until the main shock
N. V. Sarlis, E. S. Skordas, M. S. Lazaridou +1
The behavior of seismicity in the area candidate to suffer a main shock is investigated after the observation of the Seismic Electric Signal activity until the impending mainshock.…
Seismic Electric Signals and 1/f "noise" in natural time
P. A. Varotsos, N. V. Sarlis, E. S. Skordas
By making use of the concept of natural time, a simple model is proposed which exhibits the behavior with close to unity. The properties of the model are compared to th…
The fluctuations, under time reversal, of the natural time and the entropy distinguish similar looking electric signals of different dynamics
P. A. Varotsos, N. V. Sarlis, E. S. Skordas +1
We show that the scale dependence of the fluctuations of the natural time itself under time reversal provides a useful tool for the discrimination of seismic electric signals (crit…
Natural time and 1/f "noise"
P. A. Varotsos, N. V. Sarlis, E. S. Skordas
Seismic electric signals have been found to obey the ubiquitous behavior [{\em Phys. Rev. E} {\bf 66}, 011902(2002)]. The newly introduced concept of natural time enables t…
Comments on the entropy of seismic electric signals under time reversal
P. A Varotsos, N. V. Sarlis, E. S. Skordas +1
We present recent data of electric signals detected at the Earth's surface, which confirm the earlier finding [Phys. Rev. E 73, 031114 (2006)] that the value of the entropy in natu…
