Study Notes

Landslide Types

  • Falls are characterized by the free-fall of rock or debris from a steep cliff or slope
  • Flows involve the movement of unconsolidated materials like soil, mud, or debris, often with a high water content, which move downslope in a fluid-like manner
  • Slides involve the downward and outward movement of a coherent mass of rock or soil along a well-defined slip surface.

Rotational Slides

  • Rotational Slides are characterized by a curved slip surface and backward rotation of the moving mass.

Flow Slides

  • Flow Slides are characterized by the mobility of the moving mass, often resembling a fluid and featuring a high water content.
