Knot A VOLCANO is part of the Résif research infrastructure information system and concentrates seismic data from the three volcanological and seismological observatories of the Institut de Physique du Globe de Paris. These observatories operate short-seismological stations-analogical period, short-digital three-component period, medium-digital band and digital wideband. These data are used for monitoring regional volcanic and land-based activity, as well as tsunami warning. The poster presents the results at the end of 2017 and the prospects for this knot A. The French Seismological and Geodetic Network Résif is 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 integrated into European (EPOS - European Plate Observing System) and global systems of instruments for imaging the Earth's interior as a whole and studying many natural phenomena.
