P & S Waves ratio with Poisson's Ratio Curve Plot

P/S & S/R Wave Ratios vs Poisson's Ratio

This visualization shows the relationship between Poisson's ratio (σ) and the velocity ratios:

• P-wave to S-wave velocity ratio (Vp/Vs)
• S-wave to Rayleigh-wave velocity ratio (Vs/Vr)

The Poisson's ratio (σ) typically ranges between 0.0 and 0.5 for most subsurface materials.
