Abstract

Statistical laws such as the Omori and Gutenberg-Richter laws have become one of the most important tools for seismic hazard. The introduction of earthquake networks by Abe and Suzuki has opened a new research field in seismology, which gives an option to view the seismicity as a complex phenomena in an approachable way and may help to improve seismic hazard assesment. This paper intends to make a revision of the earthquake network models proposed in the literature, and to look for open questions by the date which may be of interest for future research.
