Landslides WHO Response

The magnitude of the physical and human costs from landslides can be reduced if adequate emergency prevention, preparedness, response and recovery measures are implemented in a sustainable and timely manner. 

WHO works with Member States to build resilient and proactive health systems that can anticipate the needs and challenges during emergencies so that they are more likely to reduce risks and respond effectively when needed. 

As the health cluster lead for global emergencies, WHO works with partners to respond to:

  • ensure appropriate food supplementation; 
  • restore primary care services, like immunization, child and maternal health, and mental health;
  • assemble mobile health teams and outreach;
  • conduct epidemic surveillance, early warning and response;
  • call for emergency funding to support health action

Landslides

Landslides are more widespread than any other geological event, and can occur anywhere in the world. They occur when large masses of soil, rocks or debris move down a slope due to a natural phenomenon or human activity. Mudslides or debris flows are also a common type of fast-moving landslide.

Landslides can accompany heavy rains or follow droughts, earthquakes or volcanic eruptions. Areas most vulnerable to landslides include:

  • steep terrain, including areas at the bottom of canyons;
  • land previously burned by wildfires;
  • land that has been modified due to human activity, such as deforestation or construction;
  • channels along a stream or river;
  • any area were surface runoff is directed or land is heavily saturated.
