Offshore British Columbia microseismicity

Initial and relocations of microseismicity in the Queen Charlotte triple junction and Explorer microplate region offshore British Columbia, Canada from 1995-2021. These data include detections using the Regressive Estimator (REST) algorithm and those from network analysts at the Geological Survey of Canada (GSC). The files include earthquake locations, origin times, and P and S wave travel/arrival times. Centroid moment tensor solutions from the Geological Survey of Canada.
