Pictured above is a landslide. Landslides occur when the stability of a slope changes from a stable to an unstable condition. Some natural causes for a landslide are groundwater pressure acting to destabilize the slope, earthquakes, or weakening of a slope from saturation with water. The water source originates from snow or glacier melt or heavy rains. Human activities can also form landslides from vibrations induced by machinery or traffic, blasting, or other construction activities.
