Seismic velocity and rock properties
appliedgeophysics.berkeley.eduother damping mechanisms such as viscous flow (Biot Theory) have some success but much important work remains to be done in this area (especially for unconsolidated material where the attenuation is very high). Some of the theories predict attenuation as well as dispersion (the variation of velocity with frequency).
