Geomechanical (Engineering) Properties
Seismic velocities can be related to standard geotechnical properties. For example, Poisson's ratio n can be found from:
Figures 1 and 2 show the S and P wave velocities of seismic waves for a number of different rock types.
Figure 1. S-wave velocity ranges for common materials.
Figure 2. P wave velocity ranges for common materials.
