Terradinámia is understood as the science of the penetration of the soils, it is useful to measure the thickness of the Antarctic ice and the marine sediments, among other applications. One of the main instruments that counts is a cannon developed by the laboratories Sandia de Albuquerque, New Mexico, United States. The artifact consists of a cylinder of a little more than 10 ms of length and open of the two sides, that can throw a projectile capable of penetrating 90 m under the terrestrial surface. The projectile is a heavy piece of steel (about 160 kg) containing gunpowder and a reaction mass. From the terradinámia it is also possible to introduce seismic and acoustic sensors for scientific research purposes, as well as to obtain the necessary information to elaborate a subsoil profile.
