Python-based program or processing seismic catalogs and calculating seismicity parameters for PSHA

We present a Python-based program designed for processing seismic catalogs and calculating seismicity parameters for characterizing seismogenic area sources for a probabilistic seismic hazard assessment. This tool provides detailed control over the database and every step of the processing workflow. The program enables initial spatial-temporal analyses. It also includes key functionalities such as initial attributes manipulation, event filtering, homogenization to moment magnitude (Mw), as well as estimations of the magnitude of completeness (Mc). Various declustering methods can be selected and applied by the users to identify and remove dependent earthquakes (aftershocks and foreshocks). The catalog processing ends with a completeness analysis. Additionally, it facilitates uncertainty quantification by generating synthetic catalogs through Monte Carlo simulations.
