000020162 520__ $$2eng$$aThe first version of the ISC-GEM Global Instrumental Earthquakes Catalogue (1900-2009) was released in 2013 (www.isc.ac.uk/iscgem/index.php) following the 27-month project funded by the ISC and GEM Foundation. The catalogue was constructed for use in both global and regional seismic hazard and risk assessment. The main feature of this catalogue is the improved homogeneity and accuracy of the main earthquake parameters (location and magnitude) over a 110-year period of instrumental recordings. Due to the time and resource limitations of the original project, the ISC-GEM catalogue included only earthquakes greater than or equal to the following time-variable cut-off magnitudes: M S 7.5 for earthquakes occurring before 1918; M S 6¼ between 1918 and 1959; and M S 5.5 from 1960 onwards. With further funding from several commercial and public bodies, we started working on the 4-year Extension project, adding both recent earthquakes as well as those in the early instrumental period that fell below the original cut-off magnitude of 6¼. In this article we present the updated ISC-GEM catalogue, which now includes many thousands of additional large earthquakes that occurred during the 1935-1959 period. The results of the Extension project will also be helpful for regional cross-border seismic hazard studies. The ISC-GEM catalogue is based primarily on teleseismic station readings and can be used as a reference for cross checking the consistency in location and magnitude of the same earthquakes that are listed in various regional catalogues.
