Summary
There is abundant evidence for high levels of seismic activity during deglaciation of Eastern Canada, suggesting that the seismic response of Eastern Canada to deglaciation is analogous to Fennoscandia, where numerous glacially induced faults have been confirmed. However, the Canadian record of glacially induced faults is scant. The two probable glacially induced faults that are described are few compared to the 100+ surface ruptures that are expected on statistical grounds. Alternative explanations to account for the small number of known ruptures are provided together with an interpretation of certain normal faulting that has been observed in glaciolacustrine sediments. It is recommended that the interpretation of prospective glacially induced fault features utilize a sceptical approach employing judgemental scales that reflect data limitations and associated uncertainties.
