英文摘要	We investigated post-seismic velocity changes within the fault zone of the 2008 M7.9 Wenchuan earthquake using coda wave data of repeating small earthquakes. We employed template matching and grid search methods to identify well-defined repeating earthquakes in order to minimize artefacts induced by variations in source location. We identified a total of 12 isolated patches in the fault zone that ruptured more than twice in a 1 yr period after the M7.9 earthquake. We applied the coda wave interferometry technique to the waveform data of the 34 identified repeating earthquakes to estimate velocity changes between the first and subsequent events in each cluster. We found that major post-seismic velocity changes occurred in the southwestern part of the rupture area, where the main rupture was initiated and characterized by thrust motion, while the Beichuan area in the northeastern part of the rupture zone appears to experience very little post-seismic velocity changes.
