FMC - Earthquake focal mechanisms data management, cluster and classification

Abstract Seismicity is frequently used to deduce the tectonics of a region. 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. FMC computes the different earthquake parameters that can be obtained from focal mechanism data, classifies the rupture type of each focal mechanism, performs a clustering analysis of the data if required by the user, outputs the parameters in different formats and generates a classification diagram from the input data.
