This paper presents 1 the overall procedure followed in order to assemble the most recent pan-European strong-motion databank: Reference Database for Seismic Ground-Motion in Europe (RESORCE). RESORCE is one of the by-products of the SeIsmic Ground Motion Assessment (SIGMA; projet-sigma.com) project. RESORCE is intended to be a single integrated accelerometric databank for broader Europe to understand the regional differences in seismic hazard for improving risk studies in Europe and surrounding countries. RESORCE principally updates and extends the previous pan-European strong-motion data-bank (Ambraseys in Bollettino di Geofisica Teorica ed Applicata 45:113-129, 2004a) from recently compiled Greek, Italian, Swiss and Turkish accelerometric archives. The updates also include the earthquake-specific literature studies published in recent years. The current content of RESORCE includes 5,882 multi-component and uniformly processed accelerograms from 1,814 events and 1,540 strong-motion stations. The moment magnitude range covered by RESORCE is 2.8 Mw 7.8. The source-to-site distance interval extends to 587 km and distance information is given by the common point- and extended-source distance measures. The paper presents the current features of RESORCE through simple statistics that also quantify the differences in metadata and strong-motion processing with respect to the previous version of the pan-European strong-motion databank.
