Accelerometric monitoring is carried out in mainland France and overseas. Résif-Rap has set up its stations in regions with relatively high seismicity where the risk is highest (Antilles, Alps, Provence and Pyrenees), but also in regions where the seismicity rates are more modest although not negligible (Rhine Graben, Ardennes, Armorican Massif, Central Massif, Mayotte). One of the challenges is to install the stations as close as possible to the seismic sources in order to record the strong movement at short distance (ideally less than 20 km). Résif-Rap also aims to install its stations in places that are sensitive to seismic risk: particular sites where seismic wave amplification phenomena are expected, and urban areas with high human, economic or environmental stakes.Résif-Rap is an action of the French seismological and geodetic network Résif, a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Internal Earth. Résif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Résif is part of the European (Epos - European Plate Observing System) and global systems of instruments used to image the Earth's interior as a whole and to study many natural phenomena.
