International audience; Volcanic risk at Vesuvius is one of the highest in the world due to the ~670,000 inhabitants living in the Red Zone, the area exposed to both pyroclastic flows and tephra fallout, to be evacuated before renewal of any eruptive

In the Southern Volcanic Zone (Chile-Argentina), the active Caviahue-Copahue Volcanic Complex (CCVC) is approximately 30 km east of the main N-S trending volcanic front, where the Nazca Plate subducts under the South American Plate. CCVC activity inc

There is a general agreement that fault-fracture meshes exert a primary control on fluid flow in both volcanic/magmatic and geothermal/hydrothermal systems. For example, in geothermal systems and epithermal gold deposits, optimally oriented faults an

Methane emission from the geosphere is generally characterized by a radiocarbon-free signature and might preserve information on the deep carbon cycle on Earth. Here we report a clear relationship between the origin of methane-rich natural gases and
