Coda Wave Interferometry for Estimating Nonlinear Behavior in Seismic Velocity

Roel Snieder, Alexandre Grêt, Huub Douma, John Scales

In coda wave interferometry, one records multiply scattered waves at a limited number of receivers to infer changes in the medium over time. With this technique, we have determined the nonlinear dependence of the seismic velocity in granite on temperature and the associated acoustic emissions. This technique can be used in warning mode, to detect the presence of temporal changes in the medium, or in diagnostic mode, where the temporal change in the medium is quantified.
