Additional information for the paper `Entropy of seismic electric signals: Analysis in natural time under time-reversal'
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…
Entropy of seismic electric signals: Analysis in natural time under time-reversal
P. A. Varotsos, N. V. Sarlis, E. S. Skordas +1
Electric signals have been recently recorded at the Earth's surface with amplitudes appreciably larger than those hitherto reported. Their entropy in natural time is smaller than t…
Similarity of fluctuations in correlated systems: The case of seismicity
P. A. Varotsos, N. V. Sarlis, H. K. Tanaka +1
We report a similarity of fluctuations in equilibrium critical phenomena and non-equilibrium systems, which is based on the concept of natural time. The world-wide seismicity as we…
