Abstract : The FR network code embraces most of the permanent seismic stations installed in metropolitan France and operated by academic research institutes and observatories. In 2024, it includes 198 broadband stations of the RLBP network (Réseau Large Bande Permanent, part of the national Epos-France Research Infrastructure), among which 183 are operational. Each broadband station is equipped with a wide band seismic sensor, usually having a flat response down to periods lower than 120s, and a high dynamic acquisition system. About 50 of these broadband stations also host a strong motion sensor of the RAP (Réseau Accélérométrique Permanent) French strong motion network and 10 stations host environmental sensors (pressure, temperature, wind and rain). Half (91) of the operating stations have seismometers installed in shallow depth (< 30 m) boreholes. Data are collected in near real-time via DSL, optical fiber or cellar links generally at samplig rates of 100 and 1 sample per second. Emphasis is put on the continuity of the records and on the noise level at the sites to provide high-quality data to the end users. The Epos-France Information System manages the data from the broadband stations and collocated accelerometers and freely provides both real time and consolidated data in the MiniSEED format. Quality control of waveforms and metadata updating are performed by EOST (Strasbourg) and OCA (Nice) for the RLBP and by OSUG (Grenoble) for RAP stations. Archiving and distribution of every data are carried out by the Epos-France datacentre hosted by the University of Grenoble Alpes. All together, these data are used for a wide variety of fundamental and applied studies including seismic imaging of the deep Earth, monitoring of the seismic activity in metropolitan France and adjacent regions, source studies of local, regional and teleseismic earthquakes or monitoring of seismic signals related to subsurface processes.
