Estimation Inverse Velocity Section Response on Seismic Wavefield

Summary A feature of inverted velocity sections is the presence of a low-thickness high-velocity surface layer (PVL). Such a layer can be formed by seasonally frozen and technogenically compacted soils, concrete and asphalt pavements [1, 6]. Observed on seismograms, observed according to the Y - Y observation scheme. Unlike normal sections, Love waves are not traced in inverse sections, since the conditions for their occurrence are not met. This circumstance allows us to identify useful reflected waves confined to the boundaries in the depth range from the first meters to the first hundreds of meters.
