What is Risk Analysis in the Context of Natural Disaster Events
Natural disaster risk analysis evaluates the potential impact of heavy rainfall and increased water flow on communities, transportation networks, infrastructure and essential services. Flash floods can develop rapidly in small streams, while saturated slopes can become unstable and trigger landslides or ground subsidence.
Known Hotspots and Sensitive Areas
High Impact
- Mountainous and steep-slope areas
- Small streams and drainage channels
- Communities located near unstable slopes
Medium Impact
- Rural roads and bridges
- Agricultural areas
- Low-lying settlements near waterways
Low Impact
- Elevated urban areas away from waterways
- Areas outside the warning zones
Impact on Transportation and Services
Flash floods and landslides may block roads, damage bridges and disrupt access to affected communities. Land subsidence may also create localized hazards for roads and infrastructure, particularly in areas experiencing heavy runoff.
Recommended Actions
- Avoid traveling through areas under active flood or landslide warnings.
- Monitor official weather and disaster alerts.
- Follow evacuation instructions issued by local authorities.
