Map of seismic stations before (A) and after (B) the TOPO-IBERIA IberArray, PYROPE, and OROGEN projects. Before 2010, only permanent stations form the Réseau de Surveillance Sismique des Pyrénées (RSSP) (red triangles) and from the Réseau Large Bande Permanent (RLBP) (pink triangles) in France, and from the Institut Cartogràfic i Geològic de Catalunya (ICGC) (orange triangles) and Instituto Geogràfico Nacional (IGN) (light green triangles) in Spain operated in the Pyrénées. The station coverage was considerably improved over the last decade with the PYROPE (blue triangles), TOPO-IBERIA IberArray (green triangles), OROGEN (light blue triangles), and MAUPASACQ (brown triangles) temporary experiments.
