The project has been launched jointly by the Bureau Central Sismologique Français (CNRS-University/BCSF) and the Laboratoire de Détection et de Géophysique (CEA-DAM/LDG). One of the main motivations of the project is to provide the end user with the best possible information on location and magnitude of each earthquake. So far, due to the various procedures in use in the observatories, the different locations and magnitudes of earthquakes located in the SI-Hex zone were presenting large discrepancies. In the 2014 version of the catalogue, 1D localizations of hypocentres performed with a unique computational scheme and covering the whole 1962–2009 period constitute the backbone of the catalogue (SI-Hex solutions). When available, they are replaced by more precise localizations made at LDG or, for recent times, by the regional observatories within: 1) the French Alps, 2) the southernmost Alps and the Mediterranean domain including Corsica, 3) the Pyrenees, and 4) the Armorican massif. Moment magnitudes Mw are systematically reported in the SI-Hex catalogue. They are computed from coda-wave analysis of the LDG records for most Mw>3.4 events, and are converted from local magnitudes ML for smaller magnitude events. Finally, special attention is paid to the question of discrimination between natural and artificial seismic events in order to produce a catalogue for direct use in seismic hazard analysis and seismotectonic investigations. The SI-Hex catalogue is accessible on the web site www.franceseisme.fr and contains 38,027 earthquake hypocentres, together with their seismic moment magnitudes Mw. date: 2015-01 date_type: published publication: Bulletin de la Societe Geologique de France volume: 186 number: 1 publisher: Societe Geologique de France pagerange: 3-19 id_number: doi:10.2113/gssgfbull.186.1.3 issn: 0037-9409 official_url: http://doi.org/10.2113/gssgfbull.186.1.3 access_IS-EPOS: limited owner: Publisher citation: Cara, Michel and Cansi, Yves and Schlupp, Antoine and Arroucau, Pierre and Béthoux, Nicole and Beucler, Eric and Bruno, Stéphane and Calvet, Marie and Chevrot, Sébastien and Deboissy, Alexandra and Delouis, Bertrand and Denieul, Marylin and Deschamps, Anne and Doubre, Cécile and Fréchet, Julien and Godey, Stéphanie and Golle, Olivia and Grunberg, Marc and Guilbert, Jocelyn and Haugmard, Méric and Jenatton, Liliane and Lambotte, Sophie and Leobal, Delphine and Maron, Christophe and Mendel, Véronique and Merrer, Sophie and Macquet, Marie and Mignan, Arnaud and Mocquet, Antoine and Nicolas, Marc and Perrot, Julie and Potin, Bertrand and Sanchez, Olivier and Santoire, Jean-Paul and Sèbe, Olivier and Sylvander, Matthieu and Thouvenot, François and Van Der Woerd, Jérôme and Van Der Woerd, Katia (2015) SI-Hex: a new catalogue of instrumental seismicity for metropolitan France.
