Document Summary
Landslides 1: describe how the impact of landslides depends on: population density, economic infrastructure, and. C right next to slide probably made of similar ground. E best bet tends to happen more slowly than the rest. Human and economic impacts of landslides are broadly governed by: population density (lives and injuries, cost of infrastructure (24410$, population preparedness (both) Canada: 24% of all geohazard deaths are from landslides. Reported yearly landslide fatalities are a low number 1000s or so. Most fatalities are associated with the landslide trigger (earthquakes, floods, volcanoes etc. ) Estimates: canada . 4 billion per year, us 3. 5 billion. Classified by: type of material, type of movement, rate of movement. Note: the name is usually a combination of 1 and 2: type of material. Debris (mixture of rock, earth, trees, water and whatever was on the slope: type of motion. Falls: occur on very steep slopes (usually rock, material detaches because of weakness (fractures, falls due to gravity, very fast.
