A Python package for the detection and analysis of repeating and near-repeating seismicity. EQcorrscan contains an efficient, multi-parallel, matched-filter detection routine (template-matching), as well as routines to implement subspace detection, and detection based on brightness.

Code is stored on github, the development branches are here, or the latest stable release can be found here.

EQcorrscan uses Obspy bindings when reading and writing seismic data, and for handling most of the event metadata, which ensures that detections can be easily migrated between softwares. Matched-filter correlations are calculated using openCV. OpenCV is not installed alongside EQcorrscan and must be installed before using this package.
