Fig. 2From: Monitoring of a geothermal reservoir by hybrid gravimetry; feasibility study applied to the Soultz-sous-Forêts and Rittershoffen sites in the Rhine grabenSchematics of surface gravity changes of geothermal origin. A gravimeter located at the Earth’s surface will be sensitive to effects coming from the above atmosphere and from different underground contributors (vadose zone, aquifer, geothermal reservoir)Back to article page
