Seismic Surveys

This kind of surveys represents the most reliable method for the distinction of underground stratigraphy layers with different levels of compactness adn morphology, using the determination of speed propagation of artificially generated seismic waves

Seismic surveys are used in all that works that needs to return morphology of underground through the generation of elastic surface waves
