Best, in Treatise on Geophysics (Second Edition), 2015. The basic principle of all seismic methods is the controlled generation of elastic waves by a seismic source in order to obtain an image of the subsurface. This velocity is di erent for di erent rocks and it is this di erence which is exploited in the seismic method. Seismic measurementsDepending on the travel path of the seismic wave, we differentiate between the seismic refraction method and the seismic reflection method (see also Fig. they travel underground. The seismic method makes use of the properties of the velocity of sound. 2 Seismic refraction method General This method is based on the fact that seismic … Overview of Geophysical Methods.
