attenuation:A decrease in seismic-signal amplitude as waves propagate from the seismic source. Attenuation is caused by geometric spreading of seismic-wave energy and by the absorption and scattering of seismic energy in different earth materials (termed anelastic attenuation). Q and kappa are attenuation parameters used in modeling the attenuation of ground motions.
