Vietnam Flood

Executive Summary for Flash Flood and Landslide Risk in Vietnam

The National Centre for Hydro-Meteorological Forecasting has warned of potential flash floods, landslides and land subsidence in parts of Vietnam. Areas across Ha Tinh and Dak Lak are particularly vulnerable, with risks concentrated along steep slopes, small streams and areas experiencing increased runoff. The warnings may affect road connectivity, local communities and infrastructure in vulnerable areas.

  • Risk Category: Natural Disasters
  • Severity Score: 4 / 5
  • Confidence Level: 75%

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.

Emergency Contacts

  • Emergency Services: 112
  • Police: 113
  • Fire and Rescue: 114
