Global issues earth hazards revision
Mass movement management
Evacuation of homes at risk in response to prior warnings of mass movement
Rescue workers help look for survivors after a mass movement event.
Draining water from vulnerable slopes in order to reduce the likelihood of
movement. Pipes installed in a slope or reduction in surface run off on land
Reduce deforestation/increase afforestation to reduce run off as trees
soak up water and intercept it meaning les soaks into the ground.
Land use planning not building on, above or below a vulnerable slope.
Prevention- rock bolts reinforce slopes. Steel rods are drilled through
different layers of rock in a slope, pinning the layers together, and
Predict- GPS monitors movements of slopes to predict major movements.
Predict- piezometers- bore holes drilled below a slope into the water table.
When a movement occurs in a slope, it puts pressure on the water table
raising its level and showing if a landslide will occur.
