Beligna#1: 3-component passive seismic array along the same line of the ERT section shown in Fig. 10 (the seismic line is a bit shorter). In general terms, the overall consistency of the 2D HVSR section with the ERT data is obvious. At the beginning of the line (western part), a thick soft-sediment cover creates a large HVSR peak around 2.5 Hz which is related to the low resistivity values obtained from the ERT (Fig. 10). See also the HS analysis in Fig. 15 and the single-component amplitude spectra in Fig. 17
