Landslides and Mass Movements Explained — Types, Triggers, and Slope Hazard Mitigation | Chapter 16 from Earth: Portrait of a Planet
Landslides and Mass Movements Explained — Types, Triggers, and Slope Hazard Mitigation | Chapter 16 from Earth: Portrait of a Planet Why do slopes collapse, and how can we prevent disasters? Chapter 16 of Earth: Portrait of a Planet by Stephen Marshak explores the science and hazards of landslides and mass movements—natural processes that reshape landscapes and threaten communities. For a podcast summary, watch the chapter video on YouTube , or read below for a comprehensive breakdown. What is Mass Movement? Mass movement (or mass wasting) refers to the downslope transport of rock, soil, snow, or ice under gravity. These events range from slow soil creep to rapid, catastrophic landslides and avalanches, impacting both natural landscapes and human infrastructure. Types of Landslides and Mass Movements Creep: Gradual, imperceptible downslope movement of soil and regolith. Solifluction: Slow, water-saturated soil flow, often in cold climates. Slumps: Rotational m...
