Fig. 17From: Tools for the efficient analysis of surface waves from active and passive seismic data: exploring an NE-Italy perilagoon area with significant lateral variationsBeligna#1—3-component (passive) seismic data: mean amplitude spectra for the Z [vertical] (a), EW [Radial] (b) and NS [Transversal] (c) components. The magenta points indicate the location of the 12 traces along the 55 m array. Compare with data presented in Figs. 13, 15, 16 and 18. See text for further commentsBack to article page
