Hydro-Meteorological Hazards• An average of 20 tropical
cyclones affects the country
annually• These are accompanied byheavy rains and strong windsthat may produce floods,
landslides and storm surges• Other weather systems bringrains

Key Actions for DRRM
• Know Hazards and Risks<- Hazard and Risk Assessment• Monitor<- Monitoring• Warn and Disseminate Information<- Risk Communicationi• Respond Appropriately and Timely at variouslevels<- Preparedness, Mitigation, Response, Recovery

ORGANIZATIONS INVOLVED IN NATURAL
HAZARDS AND RISK ASSESSMENT
Department of Science and Technology (DOST)PHIVOLCS– earthquake, tsunami and volcano-related hazards and scenarios

PAGASA– flood and storm surge hazard; climate change scenarios

Department of Environment and Natural Resources (DENR)
MGB – flood and landslide
NAMRIA – aerial photography and remote sensing, topographic base mapping,geoportal development

Academe*DOST funded projects: DREAM-LiDAR (LiDAR topography, floodhazards; NOAH (rain-triggered landslide, storm surge)

Hydro-meteorological Hazards Maps••

Mines and Geosciences Bureau Landslides and Flood mapped at 1:50,000
to 1:10,000 scales.
