During Rainfall Induced Landslide?

Many rainfall-induced landslides transform into debris flows

debris flows
Debris flows are fast-moving landslides that are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and often strike without warning. They occur in a wide variety of environments throughout the world, including all 50 states and U.S. Territories.

(fast-moving slurries of water, soil, and rock) as they travel down steep slopes, especially those that enter stream channels where they may mix with additional water and sediment. ...

What causes rainfall induced landslide?

Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability. Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity. Excessive water is thought to be one of the most common triggers for landslides.

What are the most common signs of rainfall induced landslides?

Landslide warning signs
  • Springs, seeps or saturated ground in areas that are not usually wet.
  • New cracks or unusual bulges in the ground, street or sidewalks.
  • Soil moving away from foundations, or the tilting or cracking of concrete floors and foundations.
  • Sunken or down-dropped road beds.
