Info
This application calculates possible velocity changes using the Coda Wave Interferometry Techniques. The application calculates the delay time between the coda waves of a pair of seismograms by applying cross-correlation at subsequent lapse times. Requires SAC format seismograms from different earthquakes recorded by the same component of the same station. For any given pair of seismograms which passed the correlation threshold selection, the output consists of percent velocity changes (and associated uncertainties) which occurred in between the two earthquakes. This can be combined with industrial data (e.g., rate of extraction / injection, front advance, etc.) to ascertain if the propagation medium suffered any significant variation of elastic properties.
