GPR uses electromagnetic waves, seismic uses seismic waves. GPR is better for shallow, high resolution surveys; seismology is better for surveys at larger scales, from small refraction surveys up to and beyond global scales sampling the earth's inner core (ever heard of helioseismology?). Electromagnetic waves are most notably reflected at high permittivity contrasts, whereas seismic waves are most notably reflected at high acoustic impedance contrasts - the two techniques depend on different geophysical properties and therefore can be complementary in geophysical surveying.
