MSNoise
A Python Package for Monitoring Seismic Velocity Changes using Ambient Seismic Noise

MSNoise is the first complete software package for computing and monitoring relative velocity variations using ambient seismic noise. MSNoise is a fully-integrated solution that automatically scans data archives and determines which jobs need to be done whenever the scheduled task is executed.

MSNoise is developed by Thomas Lecocq (Royal Observatory of Belgium, ROB) and Corentin Caudron (previously at ROB and EOSingapore, now at University of Cambridge).
