Seismic data acquisition scheme and the main types of waves according to their propagation characteristics.
P-wave velocity model obtained using seismic refraction tomography, with its interpretation.
Example of an indirect integration of geophysical data (electrical and seismic refraction tomography)
Schematic of a 2D inversion process, which uses direct problem solving (2D modelling)
Example of the H/V spectral ratios obtained in soil (top) and rock (bottom) locations. The spectral quotients for each calculation window are represented in color, and the black line represents the average of all windows together with their error bands (dashed).
Example of a seismic record with surface waves and their dispersion curve in a frequency-velocity diagram. S-wave velocity model with depth.
Model of the vertical profile of shear wave propagation velocity, obtained with the array technique.
