Map of stations (SP: short period; GN: Geophone nodes; BB: broadband; PBB: permanent broadband) deployed during the Maupasacq experiment. OSM: Oloron-Sainte-Marie; AB: Arzacq Basin; MB: Mauléon Basin; NPFT: North Pyrenean Frontal Thrust; SST: Sainte-Suzanne Thrust. The solid lines indicate some of the known faults of the area, the thin dashed line SW of the survey indicates the contact between the Labourd Paleozoic basement and the sediments of the Mauléon Basin and its equivalent along the Arbailles Massif further to the south, see Figure 2B. The thick dashed line delimits the French-Spanish border.
