In their paper (Europhys. Lett., 71 (2005) 1036), Carbone, Sorriso-Valvo, Harabaglia and Guerra showed that the “unified scaling law” for conventional waiting times of earthquakes claimed by Bak et al. (Phys. Rev. Lett., 88 (2002) 178501) is actually not universal. Here, instead of the conventional time, the concept of the internal time termed the event time is considered for seismicity. It is shown that, in contrast to the conventional waiting time, the waiting event time obeys a power law…

Seismic data are mapped to growing random networks. Vertices and edges of such networks correspond to coarse-grained events and event-event correlations, respectively. This approach turned out to

Anomalous diffusion of volcanic earthquakes

Volcanic seismicity at Mt. Etna is studied. It is found that the associated stochastic process exhibits a subdiffusive phenomenon. The jump probability distribution well obeys an exponential law,

Time Correlations of Lightning Flash Sequences in Thunderstorms Revealed by Fractal Analysis

By using the data of lightning detection and ranging system at the Kennedy Space Center, the temporal fractal and correlation of interevent time series of lightning flash sequences in thunderstorms

Characteristics of Seismic Networks in Spatial Scales

The seismic network is investigated by considering the cell resolution and the temporal causality of the earthquake from seismic data taken in southern California of USA and the results in random networks are compared to other findings which estimate the global network metrics.

Earthquake Networks as a Tool for Seismicity Investigation: a Review

Seismic hazard assessment is one of the main targets of seismological research, aiming to contribute to reducing the catastrophic consequences of strong earthquakes (e.g.,

Network structure entropy and its dynamical evolution for recurrence networks from earthquake magnitude time series

The network structure entropy provides an approach to characterize main shocks quantitatively and exhibits a peculiar behavior: it stays at a small value before main shock, jumps to a great value at the mainshock, and then recovers to normal values gradually.

Recent Progress in Some Active Topics on Complex Networks

By combining the results of different research orientations, a review of the recent advances in regards to spectral graph theory, opinion dynamics, interdependent networks, graph energy theory and temporal networks is provided.

Unified scaling law for waiting times between seismic events

The statistical properties of seismic time series, including both sequences of aftershocks, and patterns of occurrence of mainshocks, are studied. In this case, the universality claimed by Bak et al.

Fractals and Chaos in Geology and Geophysics

This book introduces the fundamental concepts of fractal geometry and chaotic dynamics. These concepts are then related to a variety of geological and geophysical problems, illustrating just what
