Description:
SPY is a Matlab algorithm that analyzes seismic waveforms in a semiautomatic way, providing
estimates of the two observables of the anisotropy: the shear-wave splitting parameters. We chose
to exploit those computational processes that require less intervention by the user, gaining objectivity
and reliability as a result. The algorithm joins the covariance matrix and the cross-correlation
techniques, and all the computation steps are interspersed by several automatic checks intended to
verify the reliability of the yields. The resulting semiautomation generates two new advantages in the
field of anisotropy studies: handling a huge amount of data at the same time, and comparing different
yields. From this perspective, SPY has been developed in the Matlab environment, which is widespread,
versatile, and user-friendly. Our intention is to provide the scientific community with a new monitoring
tool for tracking the temporal variations of the crustal stress field.
