Abstract
The picture shows the gravity measurements made in Bhutan within the framework of the ANR BhutaNepal project. This is a fundamental research project that associates about ten French laboratories (including Géosciences Montpellier, CEA and IPGP) as well as foreign universities and organizations. The project began in January 2013 and lasted 48 months. The instrument used for these measurements was a Scintrex CG5, which is part of the GMob network (Mobile Gravimetric National Park of Résif). Data from these measurements are distributed by Résif, a national research infrastructure dedicated to the observation and understanding of the Earth's internal structure and dynamics. Résif is based on high-tech observation networks composed of seismological, geodetic and gravimetric instruments that are densely deployed throughout France et lors de campagnes à l'étranger dans les zones à fort intérêt scientifique. The data collected enable the study of ground deformation, surface and deep structures, local and global seismicity and natural hazards, particularly seismic, on French territory with a high spatio-temporal resolution. Résif is integrated into the European (EPOS - European Plate Observing System) and worldwide systems of instruments used to image the interior of the Earth as a whole and to study numerous natural phenomena.
