CWIRE - Coda Wave Interferometry with Repeating Earthquakes (Version 1.0.0)

This code takes a catalog of earthquakes clustered by waveform similarity (e.g., REDPy) and processes the coda for each pair of earthquakes within each cluster/family for small, relative changes in seismic velocity. The causes of these velocity changes are a topic of active research. This code finds the optimal time stretching factor to either expand or condense one earthquake's coda waveform to match the other, with that stretching factor equal but opposite to the relative change in seismic velocity (dv/v). It then takes those pairwise measurements and uses a damped least-squares inversion to find the continuous time series that fits the pairwise measurements. Multiple time series can then be compared across the local seismic network or with other time series such as deformation.
