Seismotectonics of southeast France: from the Jura mountains to Corsica

The analysis of the seismicity catalog (1996 to 2019) covering region from Jura mountains Corsica provides a first-order image distribution earthquakes, highlighting large structures such as Briançonnais and Piedmontais seismic arcs, eastward deepening focal depths through Western Alps, several active faults (e.g. Belledonne, Middle Durance, Ligure). Over this period magnitudes are moderate mechanisms main events display diversity behaviors that can be explained by complexity different geological domains with more or less strong structural inheritage, variable rheological characteristics at scale crust joint action deformation. historical is in fairly good agreement instrumental seismicity, but earthquakes M>6 highlighted since 14th century until beginning 20th.
