Seismic Electric Signals: A physical interconnection with seismicity
Panayiotis A. Varotsos, Nicholas V. Sarlis, Efthimios S. Skordas +1
By applying natural time analysis to the time series of earthquakes, we find that the order parameter of seismicity exhibits a unique change approximately at the date(s) at which S…
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…
