ISC-GEM Global Instrumental Earthquake Catalogue (1900-2009)

This report describes the ISC-GEM Global Instrumental Earthquake Catalogue (1900-2009). The Catalogue represents a major step forward on the way to improve characterization of spatial distribution of seismicity, magnitude frequency relation and maximum magnitudes within the scope of GEM.

With a few exceptions, parameters of the catalogue are the result of computations based on the original reports of seismic stations and observatories, and every effort was made to use uniform location and magnitude determination procedures during the entire period of the catalogue.
