Reflection Seismology is a geophysical method used to explore the Earth's subsurface by analyzing seismic waves. When an energy source, like an explosion or a vibrating machine, generates waves, they travel through the Earth and reflect off different geological layers. By measuring the time it takes for these waves to return to the surface, scientists can create images of the subsurface structures. This technique is widely used in oil and gas exploration, as well as in geotechnical engineering and environmental studies. The data collected helps geologists and engineers understand the composition and arrangement of rocks, aiding in resource management and hazard assessment.
