Per Area. Make the selection of the area of interest (vermell color, download not available: The selected area is massive), in this case, Maps of cover of the sun of Catalonia format TIF with the marked option of See the selected series.
Seismic data acquisition scheme and the main types of waves according to their propagation characteristics.
Example of the record of seismic waves produced by a seismic source and detected by a group of 48 sensors. Three sectors are marked with the arrivals of the three types of waves (refracted, reflected and surface) differentiated by the arrival pattern. Each of these types is the basis of one of the seismic techniques applied to the ICGC.
P-wave velocity model obtained using seismic refraction tomography, with its interpretation.
Seismic reflection section where the variations in amplitude of the waves reflected at depth are observed. The continuity of the observed reflections allows the different subsurface structures to be delineated.
