Seismic profiling is useful for: depth profiling obtaining direct samples mapping subsurface currents determining the structure of sediments and basement rock

determining the structure of sediments and basement rock

Seismic profiling is the process of analyses of surface and subsurface characteristics of earth with respect to the seismic activities like volcanic eruption, earthquakes. These seismic activities can be measurement depending upon the type of sediments and rocks deposits at the base of the earth. It can also include striagraphy which gives idea about different layers of rocks deposition with seismic activity.
