Study Notes
Geomorphic Hazards
- Natural hazards pose threats that negatively affect the environment and human activities.
- Geomorphic hazards originate from the lithosphere and include volcanic eruptions, earthquakes, tsunamis, and mass movements such as landslides and avalanches.
- These hazards are influenced by human activities, increasing their impact.
- The consequences of geomorphic hazards include loss of life, destruction of infrastructure, disruption of communication lines, and humanitarian crises.
Landslides
- Landslides involve the sudden downward movement of a large mass of rock from steep slopes.
- Classified by factors such as movement type, material nature, and lubrication presence.
- Encompasses various mass movements of rock waste, soils, and ice.
Causes of Landslides
- Geological Causes: Involves weak or sensitive materials like fissured rocks that contribute to instability.
- Morphological Causes: Tectonic or volcanic uplift is significant in unstable regions; fluvial and glacial erosion also play a role.
- Human Factors: Activities like mining, irrigation projects, deforestation, excavation, and water leakages are major contributors to landslides.
