| Abstract | Landslides are especially damaging in Canada and despite their extensive occurrence, the exact location of instability depends on several factors and is therefore not homogeneous across the country. The
1:6 million scale landslide susceptibility map of Canada presented here is a first approximation for those individuals interested in pursuing more detailed investigations. The map has been constructed based primarily on GIS, by considering digital
layers of relevant national information including: slope angle, aspect, precipitation, permafrost, surficial geology, vegetation, distance to rivers, distance to coast (lakes and oceans) and bedrock lithology. These variables have been categorized
into several classes depending on their greater or lesser favourability to influence slope instabilities. The values assigned to each class are not equal for the whole country and vary depending on the region considered (Canadian Shield, Hudson Bay
Lowlands, or the remaining area). Broad patterns in slope instability are apparent at the national scale. |
