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…
Attempt to distinguish the origins of self-similarity by natural time analysis
P. Varotsos, N. Sarlis, E. Skordas +2
Self-similarity may originate from two origins, i.e., the process memory and the process' increments ``infinite'' variance. A distinction is attempted by employing the natural time…

P. A. Varotsos, N. V. Sarlis, E. S. Skordas +2
After the submission of the paper, three strong earthquakes with magnitude around 6.0-units occurred on October 17 and October 20, 2005, with epicenters in the Aegean Sea, at a dis…
