Document Summary
Impacts: human and economic impacts of landslides are broadly governed by, population density (lives and injuries, cost of infrastructure, population preparedness, most landslide fatalities are associated with the landslide trigger (earthquakes, floods, volcanoes, etc) Landslides in southern bc: most common in southern bc in all of canada because of all the mountains, return period is 25-70 years in southern bc. Classification of landslides: type of material, type of movement, rate of movement. The name is usually a combination of 1 and 2. Type of material: rock, soil, mud, debris (mixture of rock, soil, trees, water, and whatever was on the slope) Slow to fast usually strong material moving on planes of weakness. Flows: fluid motion: very slow to very fast, soil, mud, wet debris, flow is chaotic, water is usually very important, complex movements, combinations of mass movements, example: a slide that becomes a fall. If the movement is slow then name will be creep, soil flow, or earth flow.
