Fig. 6From: Tools for the efficient analysis of surface waves from active and passive seismic data: exploring an NE-Italy perilagoon area with significant lateral variationsSan Marco area. Comparison of the HS (active) seismic traces collected at P1 and P2 (offset 50 m for both the sites): a Z component (first arrivals highlighted by the P box relate to the P-wave refraction due to the shallow water table at P2) [P1—black line; P2—yellow line]; b R component; c T component (Love waves); d amplitude spectra for the P1 data; e amplitude spectra for the P2 data.
