Event correlation between aftershocks in the coherent noise model is studied by making use of natural time, which has recently been introduced in complex time-series analysis. It is found that the aging phenomenon and the associated scaling property discovered in the observed seismic data are well reproduced by the model. It is also found that the scaling function is given by the q-exponential function appearing in nonextensive statistical mechanics, showing power-law decay of event correlation…

An Application of the Coherent Noise Model for the Prediction of Aftershock Magnitude Time Series

This algorithm is based on the concept of natural time and exploits the complexity exhibited by the coherent noise model and exhibits the ubiquitous 1/f noise behavior for the aftershocks of strong earthquakes of magnitude Mź6.

Nonextensivity and natural time: The case of seismicity.

Natural time analysis reveals that the nonextensivity parameter q, in contrast to some published claims, cannot be considered as a measure of temporal organization, but the Tsallis formulation does achieve a satisfactory description of real seismic data for Japan for q=1.66 when supplemented by long-range temporal correlations.

Predictability of the coherent-noise model and its applications.

The threshold distribution function of the coherent-noise model for the case of infinite number of agents is studied and an analytic expression of the expectation value E(S) for the size S of the next avalanche is obtained and used for the prediction of thenext avalanche.

Nonlinear Processes in Geophysics Complex-network description of seismicity ∗

The seismic data taken in California and Japan are mapped to growing random networks. It is shown in the undirected network picture that these earthquake networks are scale-free and small-work

Sensitivity to initial conditions in coherent noise models

Abstract.Sensitivity to initial conditions in the coherent noise model of biological evolution, introduced by Newman, is studied by making use of damage spreading technique. A power-law behavior

Complex-network description of seismicity

The seismic data taken in California and Japan are mapped to growing random networks with the power-law connectivity distributions, and it is demonstrated how the present network approach reveals complexity of seismicity in a novel manner.

Earthquakes, model systems and connections to q-statistics

This work makes an attempt to review some of the recent studies on earthquakes using either real catalogs or synthetic data coming from some model systems, using q-statistics as a tool.

Analysis of return distributions in the coherent noise model.

Return distributions of the coherent noise model are studied for the system-size-independent case. It is shown that, in this case, these distributions are in the shape of q Gaussians, which are the
