AbstractThe Geological Survey of Canada has been recording digital earthquake ground motions in eastern Canada since 1970. Two recording digital networks are currently deployed; a strong-motion network and a weak-motion network. We have compiled the triggered digital ground motion records from the Etna instruments of the strong-motion network. Based on a detailed review of the records, 228 records obtained between 1997 and 2009 were associated with earthquakes and selected for processing. The selected records are from 11 earthquake events with magnitudes ranging from 3.5 to 5.5. To validate the recorded strong motion data, records obtained by the strong-motion network were compared with corresponding weak-motion records (i.e., from the same event at the same station). It was found that the records from these two networks are very close, which confirmed that both the strong motion and weak motion records accurately represent the ground motions.
