Using some new and previously published sedimentation rate data the relationship between sedimentation rate and distance from sediment source was statistically modelled for the Saguenay Fjord, Canada. Sedimentation rates obtained from these models can be used to reasonably predict the range of ages for submarine mass movements in the Saguenay Fjord. Error in the prediction is mostly associated with the natural variability of sedimentation rate. Ranges of dates were predicted for several submarine mass movements in the Upper Saguenay Fjord. In many cases the predicted date range did not correspond to the 1663 earthquake which had been previously assumed to have triggered these mass movements.
