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.

Theme IV – Understanding Seismicity Catalogs and Their Problems Catalog artifacts and quality control

2010
Man-made contaminations and heterogeneity of reporting are present in all earthquake catalogs. Often they are quite strong and introduce errors in statistical analyses of the seismicity. We discuss three types of artifacts in this chapter: The presence of reported events, which are not earthquakes, but explosions; heterogeneity of resolution of small ...

Maintenance of a seismic network in Bangladesh and an initial earthquake catalog

2021
Bangladesh is a densely populated country located on the north-eastern side of the India-Eurasia collision zone. The eastern half of the country is underlain by the seismically active Chittagong-Myanmar Fold and Thrust Belt, which forms the accretionary prism associated with the eastward-subducting Indian Plate, and is bordered to the north by the ...

Complex seismicity features observed in a high-resolution seismicity catalog for the Gulf of Corinth, Greece

Recent advances in seismology through newer machine learning based tools, template matching and double difference relocation allow to build high quality earthquake catalogs from continuous waveforms. Here, we apply a workflow combining these approaches and reducing computational cost to the Corinth Gulf, Greece.
