The St. Lawrence estuary is considered as one of the high-hazard seismic zones in eastern Canada. This could be associated not only with naturally-occurring earthquakes, as in the Charlevoix region, but also with induced-earthquakes triggered by man’s activity, such as the filling of certain reservoirs near Manicouagan. In this study, we used a two-dimensional numerical linear model to simulate a possible tsunami resulting from a large hypothetical earthquakes in the Charlevoix area. The duration of the earthquake was taken as 5 seconds and bottom uplifts ranging between 2 and 5 m. The results obtained from all numerical simulations show that tsunami waves with amplitudes ranging between 1 and 2 m propagated more rapidly along the relatively deeper north shore and in the downstream direction. Tsunami hazards in the Charlevoix area at any locality depend on the location of the epicentral area and magnitude of the earthquake in addition to the morphology of that locality. We are presently developing a non-linear numerical model, using an irregular triangular grid to better represented the highly variable depth pattern in the estuary. |
