SUMMARY The Lacq area in southwest France has been associated with continuous moderate induced seismic activity since 1969. However, the mechanisms driving this seismicity are not fully understood: reservoir depletion proposed as main factor, and more recently wastewater injection suggested to play a important role. interpretation of these relies heavily on quality earthquake locations, which we prove be weak due lack local instrumentation for several years. In order provide most complete...
Abstract The 2020 Alex storm in southern France led to localized extreme rainfall exceeding 600 mm less than 24 hr. In the 100 days following storm, a series of small earthquakes swarm occurred beneath Tinée valley, region characterized by low background deformation. To gain insight into mechanisms controlling evolution, we used an enhanced seismic catalog detect 188 events. These events exhibited magnitudes comprised between −1.03 and 2.01, 78 them were relocated using relative locations at...
The geodynamic complexity of the Southwestern Alps (France, Italy) comes from its strong tectonic inheritage due to European-African plates convergence. motion being currently mainly accommodated along Maghrebides, this region only registers small moderate seismicity linked low-deformation rates (convergence 0.3-0.9 mm/yr). Hence until now, geometry active faults in remains unclear and imprecise. Yet, a better knowledge these is prerequisite for establishment regional deformation model...
On 2nd October 2020, an unusual extreme rainfall event (600 mm) associated with the devastating “Alex storm” occurred in less than 24 hours Tinée valley, a low strain rate area (convergence rates of 0.3-0.9 mm/yr) Southern French Alps, located 20 kilometers from Nice city. This transitional zone between Argentera Mercantour exhumed Alpine massif and Nice/Castellane Arc, mainly filled Cenozoic sediments covering inherited structures, has no clear active faults...
