A simplified Python toolkit for earthquake catalogue manipulation and homogenisation

The toolkit consists of 12 main modules:

• Catalogue - The main module for database manipulation an I/O
• Parsers - Ad-hoc parsers for specific catalogues and bulletins (ISC, GCMT...)
• Selection - Functions for high-level manipulation of catalogue objects
• Exploration - Functions to explore database information and perform basic statistical analysis
• Regressor - Utilities for magnitude conversion and catalogue homogenisation
• Declusterer - Aftershock/Foreshock removal algorithms
• Seismicity - Functions to calculate occurence rates and fit magnitude-frequency distributions
• MagRules - Library of magnitude conversion functions
• MapTools - Utility to plot earthquake databases on a map
• Converters - Utility to convert to other formats
• IscWeb - API to download isf catalogues from the ISC web
• IscCode - ISC agency code list

OQ-CATK requires the following dependencies:

• NumPy/Scipy
• Matplotlib
• Basemap
