Seismic survey and an example of seismic data. (a) Illustration of acquisition geometry. (b) Geophones and cables spread over the ground during data acquisition. (c) Example of a raw shot-gather from the Katraj profile (KJP1) showing the surface waves and head waves (first breaks). (d) Phase velocity frequency data example. The cyan dots were picked corresponding to the fundamental mode of frequency at maximum semblance. The picked dispersion curve was then used in the inversion process.
