Title: On the choice of size distributions for earthquakes modelling Authors:  Christophe Ley - Ghent University (Belgium)

Abstract: Power-law models are very popular in several environmental and geo-physical applications: in particular, empirical evidence with major implications stems from earthquake modelling. Departing from the Gutenberg-Richter law for magnitude and seismic moment, many research efforts are continuously addressed to the proposal of candidate size distributions for seismic events. Indeed, the accurate modelling of earthquake sizes is the first priority before a step forward in the joint modelling of time and space could be taken. A critical overview of the topic is provided by advancing a model able to fit also the temporal dimension of the phenomenon. For illustrative purposes, data concerning the Pacific Ring of Fire have been considered.
