Session 2.2 GNGTS 2023 Fig. 2. Map of the resonance frequencies f0 obtained from NHV analysis. The color and size of the triangles indicate f0 and the corresponding amplitude of the NHV curve at the sites. The values of f0 were interpolated using the Natural Neighbor Interpolation method. White diamonds indicate flat or nearly flat curves
