| Description | The Western Canada Deformation Array (WCDA) is a permanent GNSS monitoring network established by the Geological Survey of Canada (GSC), Natural Resources Canada (NRCan). The network supports investigations of crustal deformation and earthquake-related processes in southwestern British Columbia and contributes to a broader multidisciplinary effort to assess regional seismic hazards. Responsibility for the operation and management of the network was transferred to the Canadian Hazards Information Service (CHIS), NRCan, in 2017. High-rate and standard 30-second GNSS observation data are collected continuously and distributed in RINEX format through the International GNSS Service (IGS) global data centres. |
