This picture shows the entrance of the former iron mine of Neufchef which gives access to the NEUF seismological station. This seismological station, whose sensor is a Trillium-120QA (surface velocimetric sensor), is located in a gallery not used by the mine's tourist circuit. The NEUF seismological station was installed by the team of the Observatoire sismologique du Nord-Est de la France (Obsnef) and is integrated into the Permanent Broadband Network (RLBP) of the national research infrastructure Résif, dedicated to the observation and understanding of the internal Earth structure and dynamics. 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.
