Fig. 3From: An experimental approach to unravel 2D ground resonances: application to an alluvial-sedimentary basinGeologic map of the Bolzano alluvial-sedimentary basin and locations of the single-station microtremor measurements. The blue square indicates the location of the measurements shown in Fig. 4. Geologic data from Keim et al. (2013). Letters A and B identify the line along which the data shown in Fig. 5 were acquired. Geologic data from Keim et al. (2013)Back to article page
