French seismological and geodetic network Résif

Résif – the French seismological and geodetic network –  was launched in 2009 in an effort to develop, modernize, and centralize geophysical observation of the Earth’s interior.


This national research infrastructure uses both permanent and mobile instrument networks for continuous seismological, geodetic and gravimetric measurements. The collected data reveal both the structure and dynamics of our planet. These data also contribute to the sustainable management of natural resources and to natural geohazard mitigation. Résif-Epos is France’s major contribution to the European infrastructure European Plate Observing System (EPOS).


The CNRS National Institute for Earth Sciences and Astronomy coordinates the Résif-Epos consortium which includes of a majority of French universities and organizations involved in geoscience research. More than a hundred researchers, engineers and technicians work together on a daily basis thus making Résif-Epos a tremendous scientific tool available to the global Earth Sciences community.
