FMC - A One-Liner Python Tool for Earthquake Focal Mechanisms Data Management, Cluster and Classification
Abstract
The study of earthquakes as a tectonic component, seismotectonics, has grown as one of the key research areas on active tectonics, especially from the analysis of earthquake focal mechanisms. Because of the continuous increase in data available in earthquake focal mechanism catalogs, we need new tools to analyze them systematically. In order to represent focal mechanism populations, different diagrams to visualize focal mechanism data as a function of the rupture has been proposed. The clustering analysis of focal mechanism populations has also been explored, but no specific software has been developed to date. The aim of the FMC program is to provide a simple but powerful tool to manage focal mechanism data, classify the events according to the earthquake double-couple (DC) rupture type, and optionally perform a clustering analysis and plot a classification diagram based on DC characteristics. The combination of these functionalities allows a deeper analysis of earthquake ruptures in a region, providing greater insight into the tectonic processes responsible for the seismicity. The program has been designed with the modularity and versatility of the classical UNIX-like tools. It is called from the command line and can be easily integrated into shell scripts (*NIX systems) or batch files (DOS/Windows systems).
