In this work, we introduce a new methodology to construct a network of epicenters that avoids problems found in well-established methodologies when they are applied to global catalogs of earthquakes located in shallow zones. The new methodology involves essentially the introduction of a time window which works as a temporal filter. Our approach is more generic and for small regions the results coincide with previous findings. The network constructed with that model has small-world properties… 

Correlation Properties in Worldwide and Synthetic Earthquake Networks

In this work, we studied the correlation properties of seismic networks by analyzing the assortativity of worldwide and synthetic earthquake networks. We used data from the World Earthquake Catalog

Statistical properties of complex network for seismicity using depth-incorporated influence radius

In recent years, seismic time series has been used to construct complex network models in order to describe the seismic complexity. The effect of the factor focal depth has been elided in some of

From spatio-temporal data to chronological networks: an application to wildfire analysis

The proposed chronological network construction process that is capable of capturing various events is computationally efficient, adaptable to different time windows and can be applied to any spatiotemporal data set.

Dynamic Community Detection into Analyzing of Wildfires Events

This work investigates the information that dynamic community structures reveal about the wildfires’ dynamics using the chronological network concept—a temporal network where nodes are linked if two consecutive events occur between them—to reveal wildfire patterns observed throughout the year.

The architecture of complex weighted networks.

This work studies the scientific collaboration network and the world-wide air-transportation network, which are representative examples of social and large infrastructure systems, respectively, and defines appropriate metrics combining weighted and topological observables that enable it to characterize the complex statistical properties and heterogeneity of the actual strength of edges and vertices.

Dynamical and correlation properties of the internet.

It is found that the Internet is characterized by non-trivial correlations among nodes and different dynamical regimes, and the importance of node hierarchy and aging in the Internet structure and growth is pointed out.

Fast unfolding of communities in large networks

This work proposes a heuristic method that is shown to outperform all other known community detection methods in terms of computation time and the quality of the communities detected is very good, as measured by the so-called modularity.

Sensitivity to initial conditions in the Bak-Sneppen model of biological evolution

Abstract:We consider biological evolution as described within the Bak and Sneppen 1993 model. We exhibit, at the self-organized critical state, a power-law sensitivity to the initial conditions,
