A seismic survey is a method of investigating the subsurface of the earth using sound waves. Seismic surveys are used to map the structure and composition of the earth’s crust and can be used to locate petroleum, natural gas, minerals, and groundwater.
Seismic surveys are conducted by sending out sound waves into the ground and measuring the time it takes for them to bounce back. The data collected from these measurements is then used to create a three-dimensional model of the earth’s crust.
Seismic surveys have been used since the early 1900s and have become an invaluable tool for geologists and other scientists who study the earth’s surface.
