Abstract
We compare erosional processes on two different types of continental slopes: Verrill Canyon slope (Nova Scotia) is part of a mature glacial margin and Meriadzek is a portion of a starved periglacial margin (Celtic Margin). Physical properties of sediments, more than slope angle or sediment volume, appear as the main controlling factor for slope failure conditions. High cohesion and high bulk density characterize giacial sediments and up to 25 m of sediment may stay stable in the absence of an earthquake. In contrast, on the peri-glacial margin, a thinner layer of up to 8 m thick may be susceptible to sliding by sediment loading. This observation seems to be a general characteristic of North Atlantic margins during the Quaternary.
