On the anomalous {changes of seismicity and} geomagnetic field prior to the 2011 9.0 Tohoku earthquake
E. S Skordas, N. V. Sarlis
Xu et al. [J. Asian Earth Sci. {\bf 77}, 59-65 (2013)] It has just been reported that approximately 2 months prior to the 9.0 Tohoku earthquake that occurred in Japan on 11 Ma…
Fluctuation theorem and natural time analysis
N. V. Sarlis, P. V. Varotsos, E. S. Skordas
Upon employing a natural time window of fixed length sliding through a time series, an explicit interrelation between the variability of the variance ()…
Order parameter fluctuations in natural time and b-value variation before large earthquakes
P. A. Varotsos, N. V. Sarlis, E. S. Skordas
Self-similarity may stem from two origins: the process' increments infinite variance and/or process' memory. The -value of the Gutenberg-Richter law comes from the first origin.…
Effect of significant data loss on identifying electric signals that precede rupture by detrended fluctuation analysis in natural time
E. S. Skordas, N. V. Sarlis, P. A. Varotsos
Electric field variations that appear before rupture have been recently studied by employing the detrended fluctuation analysis (DFA) as a scaling method to quantify long-range tem…
Detrended fluctuation analysis of the magnetic and electric field variations that precede rupture
P. A. Varotsos, N. V. Sarlis, E. S. Skordas
Magnetic field variations are detected before rupture in the form of `spikes' of alternating sign. The distinction of these `spikes' from random noise is of major practical importa…
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.…
