Beligna#1—central area (HS1). Joint analysis of the active HS and passive HVSR data: a group velocity spectra of the Z component; b group velocity spectra of the R component; c field (green lines—shown the mean curve and the standard deviation) and synthetic (blue line) HVSR curves; d obtained VS profile (down to 400 m); e close-up of the shallow part (first 15 m) of the obtained VS profile. The HVSR peak at about 0.43 Hz is related to the deep bedrock
