GPR (Ground Penetrating Radar) utilizes electromagnetic waves, making it ideal for shallow, high-resolution surveys, while seismic methods employ seismic waves suitable for larger-scale investigations. The fundamental difference lies in the types of waves used: GPR reflects at high permittivity contrasts, whereas seismic techniques reflect at high acoustic impedance contrasts. Both methods can be complementary in geophysical surveying, each offering unique advantages based on the specific properties being examined. GPR excels in detailed subsurface imaging, while seismic methods are effective for broader geological assessments, including deep Earth studies. Understanding these differences enhances the application of both techniques in geophysical research.
