Document Summary

Risk analysis for landslides (mass wasting is the downslope movement of solid earth materials by gravity. : understand the hazard in general. Determine the triggering effects (eg, rainfall, earthquakes, human action, etc). Determine the slope"s steepness (the steeper, the more likely a landslide will occur). Determine the nature of the material (soil will slide down at smaller angle than rocks/ice). Determine how much internal strength there is. Determine the friction of the material on the mountain. Landslides are classified based on mechanism (flow, slip, fall) and velocity (low to high). (low) Avalanche (active on permafrost) (low water content) (high water content) (rock or debris) Fall: determine the risk from that hazard in a particular area (risk = ph x sh). Determine the nature of slopes in the area (there are slopes everywhere). Use photographs taken from the air/space to look for ancient slide scars. Study the history of landslides in the area.
