Main Article Content
The main purpose of this paper is to provide a tutorial application of SEDAv1.0, the first version of a software package, recently designed for the statistical analysis of earthquake data. SEDAv1.0 consists of a user-friendly Matlab-based interface, to facilitate the interaction with the application, and of a computational core of Fortran codes, to guarantee fast running times.
The main part of SEDAv1.0 is devoted to the ETAS modeling. For the first time, an almost complete set of consistent tools based on ETAS models is collected in a single, free software. Moreover, SEDA guarantees the research reproducibility, which is becoming an increasingly major concern among scientists.
The peculiarities of some routines of SEDAv1.0 are discussed in this paper, by the application to two important recent seismic sequences occurred in Italy. Specifically, the paper illustrates how using SEDAv1.0, to estimate the completeness magnitude and the b-value, to set and test the ETAS model and, finally, to identify the earthquakes sequences, basing on causal connections.
