ARRAY CABLE FOR SEISMIC PROSPECTION, PUR YELLOW CABLE The seismic exploration of refraction type is among the most diffused and used active seismic methods. This type of survey has the purpose to determine the thickness of the overburdens (aerated) above a rigid sub-layer and reconstruct a seismic stratigraphic sequence in terms of apparent longitudinal speed. If carried out according to more sophisticated calculation methods, it can be used to intercept, measure and characterize geo-structural profiles. Seismic exploration of refraction type is carried out by placing equidistant geophones in line on the ground, and generating seismic pulses through mechanical “inputs”. Then the travelling times of the pulses that once penetrated in the ground are refracted nearby the lithological passages at different density, will be measured. The seismic exploration of reflection type, which is extensively used in oil explorations, is also used nowadays to obtain detailed information on surface soils. Due to the high resolution of the survey, it is used to define the development of geological structures in the sub-soil, defining the shapes, sizes and positions. The prospecting is carried out by placing high frequency geophones in line and close to each other, sending seismic pulses through energy (also at high frequency) and by measuring the travelling times of the waves that, once penetrated in the ground, are reflected by the uneven surfaces that delimit the lithological passages with net impedance contrast.
