Using coda wave interferometry for estimating the variation in source mechanism between double couple events

Robinson, David; Snieder, Roelof K; Sambridge, Malcolm


It is shown how a change in orientation between the source mechanism of two identically located double couple sources can be estimated from the correlation of the coda waves excited by their sources. The change in orientation is given by the root mean square of the change in strike, Δφs, dip, Δδ and rake, Δλ of the double couple. It is not possible to determine Δφ s, Δδ or Δλ individually from the cross correlation. Applicability of the theory is tested using synthetic waveforms generated from...[Show more]
