Seismic exploration includes geophysical methods of studying the Earth's crust, which are based on the study of artificially excited elastic waves. Seismic exploration is used to study the deep structure of the Earth and to find deposits of minerals (mainly oil and gas), to solve problems of hydrogeology and engineering
geology. Seismic survey is very reliable, it can obtain a huge amount of information. Big profit recoups the work of numerous expensive equipment that comes to the places which have never had any roads at all... Now we are going to spend some time with a seismic crew and see how they work.
