Bella Coola Seismicity Data

Microseismicity in the western Coast Mountains of British Columbia in the Bella Coola region. Includes initial and relocations of seismicity, P-wave velocity model and station location information, and focal mechanism solutions. These data include detections using the Regressive Estimator (REST) algorithm and those from network analysts at the Geological Survey of Canada (GSC).
