Seismic Refraction Prospecting for Groundwater: A Case Study of …
WebDisadvantage. Advantage. Disadvantage. Refraction observations generally employ fewer source and receiver locations and are thus relatively cheap to acquire. Because many source and receiver locations must be used to produce meaningful images of the Earth's subsurface, reflection seismic observations can be expensive to acquire. WebSeismic tomography or seismotomography is a technique for imaging the subsurface of the Earth with seismic waves produced by earthquakes or explosions. P-, S-, and surface waves can be used for tomographic models of different resolutions based on seismic wavelength, wave source distance, and the seismograph array coverage.
