RAY SYNTHETIC SEISMOGRAMS (Chapter 6) - Seismic Ray Theory

WebJul 2, 2001 · The seismic ray method plays an important role in seismology, seismic exploration, and in the interpretation of seismic measurements. Seismic Ray Theory … WebSeismic Ray Theory · When seismic rays travel through the Earth, they encounter changes in K, G and ρ. This causes the rays to be reflected and refracted. · When seismic energy travels, it ideally would do so in an approximately spherical way: · The energy at the wave front gets weaker as it moves from its source. dc metro police phone number
