TRAVELS IN THE CANADIAN CORDILLERA (2008)

The travel angles of landslides are important parameter in risk analyses. Here we examine the first use of the concept in Canada, applied to the Frank slide. We also report on travel angles of an additional 61 long runout landslides in the Canadian Cordillera, mostly in northern BC. The lowest travel angles we report belong to the following groups (in ascending order) sensitive glaciomarine sediments, earth flows generated by rock slides, diamicts derived from clay shales, advance phase glaciolacustrine sediments, rock avalanches on glaciers, rock slide – debris flows, rock slide debris avalanches, and rock avalanches in general.
