It is widely accepted that the observed earthquake scaling laws indicate the proximity of the system to a critical point. Using the order parameter (OP) for seismicity suggested on the basis of natural time as well as the detrended fluctuation analysis of the magnitude time-series, we investigate the behavior of seismicity before and after significant earthquakes. The analysis reveals that the fluctuations of the OP before major earthquakes exhibit a characteristic feature which, if quantified… Expand

Abstract. Self-similarity may stem from two origins: the process increments infinite variance and/or process memory. The b-value of the Gutenberg-Richter law comes from the first origin. In the frameExpand

Multiple-time scaling and universal behavior of the earthquake interevent time distribution.
TLDR
It is shown that the interevent time distribution exhibits a universal behavior over the entire temporal range if four characteristic times are taken into account and provides a tool to identify the dependence on the mainshock magnitude of the c parameter that fixes the onset of the power law decay in the Omori law.

Structure of fluctuations near mean-field critical points and spinodals and its implication for physical processes.
TLDR
The structure of fluctuations near critical points and spinodals in mean-field and near-mean-field systems and the way that they form fluctuations has important physical consequences for phenomena as diverse as nucleation in supercooled liquids, spinodal decomposition and continuous ordering, and the statistical distribution of earthquakes.

Effect of extreme data loss on long-range correlated and anticorrelated signals quantified by detrended fluctuation analysis.
TLDR
This paper investigates how extreme data loss affects the scaling behavior of long-range power-law correlated and anticorrelated signals, and finds that the average length mu_{r} of the remaining segments is the key parameter which determines the scales at which the local scaling exponent has a maximum deviation from its original value.
