The NEIC global earthquake bulletin is called the Preliminary Determination of Epicenters or PDE, and is one of many discrete products in the ANSS Comprehensive Catalog (ComCat). We use the word "Preliminary" for our final bulletin because the Bulletin of the International Seismological Centre is considered to be the final global archive of parametric earthquake data, in other words phase arrival (“pick”) times and amplitudes.

The ANSS Comprehensive Catalog (ComCat) contains earthquake source parameters and other products produced by contributing seismic networks. Important digital catalogs of earthquake source parameters (e.g. Centennial Catalog, Global Centroid Moment Tensor Catalog) are loaded into ComCat. New and updated data are added to the catalog dynamically as sources publish or update products. Access to the ComCat is via the online search page, on which a user can select a wide variety of criteria to locate earthquake events of interest. Source Parameters: -amplitude - hypocenter - magnitude - phase data - finite fault - focal mechanism - moment tensor - tectonic summary - regional information Products: - Did You Feel It? -...
