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…

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…
