Session 1.1 GNGTS 2023 Fig. 3: a) left: map view of CLASS (red dots) and CARS (black dots) locations, in the Irpinia 1980 seismic sequence area (small green box in the inset); right: CLASS (top, red dots) and CARS (bottom, black dots) locations represented in cross-sections within +/- 5 km of from the trace represented in map-view; b) CLASS and CARS locations in between Sicily and Calabria (big white box in the inset); right: map view of CLASS (top) and CARS (bottom) locations; left: CLASS (top) and CARS (bottom) locations within +/-50 km from the trace represented in the corresponding map-view; blue lines correspond to the two different 1D velocity models zones from Pastori et al. B2-2019-2021, Wp1-task4.
