New GPS estimates of relative motion across the Jura Mountain Belt with respect to the Eurasian Plate indicate less than 1 mm/yr of convergence, considerably less than previous estimates. Velocity uncertainties have been evaluated by several methods and range from 0.2 to 0.5 mm/yr for the semi-permanent stations. The major,...

The Rhône River Valley in France, a densely populated area with many industrial facilities including several nuclear power plants, was shaken on November 11th 2019, by the Mw 4.9 Le Teil earthquake. Here, we report field, seismological and interferometric syntheticaperture radar observations indicating that the earthquake occurred at a very...

Based on new geological data and analysis of Digital Elevation Model, we update the active fault mapping and determine earthquake geology hints of a section of a major crustal active fault system of continental Ecuador, namely the Pallatanga Fault to its junction with the Cosanga Fault, a part of the continental-scale dextral shear zone between...

Based on new geological data and the analysis of a 4 m spatial resolution Digital Elevation Model (DEM), we provide a detailed and comprehensive description of section of the Chingual Cosanga Pallatanga Puna Fault System, a major active fault system in Ecuador. This work allows estimating new slip rates and large earthquakes parameters...

Une nouvelle combinaison de 10 ans de données GPS permanents, en particulier par le réseau Rénag et d'un siècle de données de nivellement montre de façon cohérente que les Alpes occidentales sont caractérisées par des mouvements verticaux en surrection rapide, jusqu'à 2,5 mm/an au NW de l'arc, alors que les mouvements horizontaux aux limites de...

The analysis of the seismicity catalog (1996 to 2019) covering the region from the Juramountains to Corsica provides a first-order image of the distribution of earthquakes, highlightinglarge structures such as the Briançonnais and Piedmontais seismic arcs, the eastward deepeningof the focal depths through the Western Alps, several large active...

The 11-11-2019 Le Teil earthquake (Mw4.9), located in the Rhône river valley occurred along the La Rouvière fault (LRF) within the NE termination of the Cévennes faults system (CFS). This very shallow moderate magnitude and reverse-faulting event inverted an Oligocene normal fault which was not assessed to be potentially active, causing surface...
