- Human Activity on Mass Movements
- excavations
- ground is removed to make ground more level for quarries
- slope too steep = unstable
- ground is removed to make ground more level for quarries
- waste heaps
- waste heaps from quarrying have steep slopes + highly porous
- example - Aberfan
- loading by building
- increased mass increases landslip liability
- loading by water
- saturated rocks making them unstable
- if saturated rocks shaken by a landslide liquefication might occur
- saturated rocks making them unstable
- removal of vegetation
- increase surface run off + mudflows
- traffic vibrations
- quarrying + mining
- blasting techniques - directly break down rock to retrieve ores + vibrations cause movement in particles
- excavations
