Seismology utilizes the Vp/Vs ratio rather than Vs/Vp to characterize lithology and fluid content
the verdict
SUPPORTED
the evidence backs this
confidence 83/100
Seismology and rock physics standardly rely on the compressional-to-shear velocity ratio (Vp/Vs) to characterize subsurface lithology, pore fluids, and gas saturation.
