Most analogue, non-communicating instruments have been replaced with modern digital instruments that provide information in real-time. Dense networks are being deployed in the urban centres of southwest British Columbia to provide shaking parameters and “shake maps” immediately after an earthquake. Monitoring of critical infrastructure, including bridges, dam sites and transmission facilities is increasing. This article documents the current state of strong motion monitoring across Canada, and summarises the data sets that are currently available. As of 2008, the Geological Survey of Canada operates 110 strong motion instruments (Internet Acclerometers or IA’s) across Canada, most of which are deployed in the urban centres of high seismic hazard in southwest British Columbia. Partner organisations operate an additional 70 strong motion instruments monitoring critical infrastructure in western Canada. In eastern Canada, the GSC operates a network of 18 strong motion instruments in the active Charlevoix zone, and 6 IA’s in greater Ottawa. Partner organisations operate instruments at an additional 15 sites. During the past decade, more than 700 three component accelerograms have been recorded across Canada. While some large ground motions have been recorded (peak ground acceleration (PGA) greater than 2g), most of the records represent weak motion (PGA less than 5%g). These are useful for evaluating local site response, which in turn will be valuable to engineers evaluating strong ground shaking during future earthquakes.
