Seismic network XT: CIFALPS-2 temporary experiment (China-Italy-France Alps seismic transect #2

Temporary seismic array of broadband stations deployed along a transect across the northwestern Alps (France and Italy). Duration: 14-15 months. 43 stations in a 400-km long linear array, from eastern Massif Central (France) to the Ligurian coast (Italy) across the Mont Blanc and Gran Paradiso massifs; 7 km average spacing. Two additional short lines of 6 stations each 20 km to the NE and SW of the main line in the region between the cities of Aosta and Ivrea (Italy). Goal: imaging of the crust and upper mantle using earthquakes and noise records. Sensors: mostly Nanometrics Trillium Horizon, with a few Guralp CMG40T (30 or 60s). Digitizers: Nanometrics Centaur and a few Taurus.
