![]() An excellent discussion on toppling instability is presented in Goodman (2013). Examples of toppling-induced landslides in foliated metamorphic rock types are provided in Newman (2013) and Clayton (2014). Like Ã…knes, this slide comprises multiple blocks and is located in metamorphic mica schist, gneiss, and quartzite. ![]() ![]() A major slope dewatering scheme was developed to ensure stability an excellent discussion of the characterisation and modelling of this landslide is presented in Kalenchuk (2010). The toe of this landslide was submerged by a reser- voir impounded by the Revelstoke Dam, and hence this landslide has been extensively investigated. The Downie Slide in British Columbia, Canada, is the largest prehistoric landslide in North America with an estimated volume of 1.5 billion m 3. Such movement of blocks is not uncommon and shows the importance of understanding three-dimensional geological structure. ![]() multiple blocks involved in the movement with different rates and movement directions these may be related to three-dimensional variations in the geological structure along the basal sliding surface.
