Week 8
Morocco is affected by several types of mass movements, primarily due to its diverse topography, geological features, and climatic conditions. The main types of mass movements in Morocco include: 1. Landslides (Glissements de terrain) Common in mountainous regions such as the Rif, High Atlas, and Middle Atlas . Triggered by heavy rainfall, earthquakes, deforestation, and human activities like road construction . Areas with weak geological formations (e.g., clay-rich soils) are particularly prone. 2. Rockfalls (Chutes de roches) Occur in steep, rocky terrains, particularly in the Atlas Mountains and Rif region . Often caused by erosion, freeze-thaw cycles, and seismic activity . Poses risks to roads, villages, and infrastructure in mountainous areas. 3. Mudflows & Debris Flows Occur during intense rainfall or flash floods , particularly in arid and semi-arid regions. Can sweep away roads, houses, and agricultural land. The Ourika Valley disaster in 1995 is a well-known ...
