Hazard Guide
Landslide
Slope failures triggered by rainfall, erosion, or instability that can damage roads, homes, and utilities.
Overview
Understanding Landslide
Landslides are more likely during intense or prolonged rainfall, especially on unstable or altered slopes.
Overview
Summary
A landslide is the movement of rock, soil, or debris down a slope due to gravity. Landslides can be triggered by heavy rainfall, earthquakes, or human activities such as construction and deforestation. They can occur suddenly and cause significant damage to property and loss of life.
Preparedness
Preparedness
Being prepared can reduce the risks associated with landslides:
- Know if your area is prone to landslides, especially if you live near slopes, hills, or mountains.
- Watch for warning signs such as cracks in the ground, leaning trees or poles, or unusual sounds like rumbling.
- Stay informed through weather alerts, especially during heavy rainfall.
- Prepare an emergency kit with essentials such as water, food, first aid supplies, and important documents.
- Develop an evacuation plan and identify safe areas away from slopes and low-lying zones.
Prevention
Prevention
While not all landslides can be prevented, risks can be reduced by:
- Maintaining proper drainage systems to prevent water buildup in soil.
- Avoiding deforestation and protecting vegetation that helps hold soil in place.
- Following safe construction practices and avoiding building on unstable slopes.
- Installing retaining walls or barriers where necessary.
- Managing land use carefully in high-risk areas.
Response
Response and Safety Measures
If a landslide occurs or is imminent:
- Move quickly away from the path of the landslide to higher, stable ground.
- Avoid river valleys and low-lying areas where debris may flow.
- Follow instructions from local authorities and emergency services.
- If you are indoors, evacuate immediately if it is safe to do so.
- Seek medical attention if injuries occur and report hazards to authorities.
