SHARE European Earthquake Catalogue (SHEEC) 1000-1899

The SHARE European Earthquake Catalogue (SHEEC) 1000-1899 has been compiled in the frame of the EC project "SHARE" (Seismic Hazard Harmonization in Europe; 2009-2012).nIt relies on the experience of the EC I3 project "Network of Research Infrastructures for European Seismology" (NERIES; 2006-2010), a module of which was dedicated to create the Europeann"Archive of Historical Earthquake Data" (AHEAD) and to establish methodologies to homogenously derive earthquake parameters from macroseismic data.nAHEAD has supplied the final earthquake list, obtained after sorting duplications out and eliminating many fake events, and the most updated historical dataset.nEarthquake parameters have been obtained by:n- processing macroseismic data points (MDPs) provided by AHEAD, with updated, repeatable procedures, regionally calibrated against a set of recent, instrumental earthquakes;n- the most updated regional parametric catalogues, re-assessing Mw;n- selecting the most reliable epicentral location between a) and b) and assessing a final Mw value as a weighted mean of a) and b).
