Background: The Hazardscape of Philippines
The geographic and geologic setting of the Philippines (part of Pacific Ring of Fire and Earthquake Belt) make it prone to various hazards, including:
weather and climate-related volcano-related earthquake-related (tsunami) Three of deadliest typhoons
occurred the past three years: Dec 2011 – TS Washi – 1,268 Dec 2012 – TY Bopha – 1,901 Nov 2013 – TY Haiyan – 6,300

Covers 300 other river systems in the Philippines
Will prioritize floodplain areas then the upland areas
Government agencies are asked to send priority sites for flight planning purposes

HAZARD MAPPING OF BARANGAYS IN EASTERN VISAYAS (REGION 8)
In partnership with United Nations Development Program (UNDP)
51
Objective
• Provide multi-hazard maps (flood, landslide, and storm surge) to 1810 identified barangays in Region 8 covering the provinces of Leyte, Samar, Eastern Samar, and Biliran.
• Print the maps in tarpaulins and distribute it to beneficiary barangays
52
SAMPLE FLOOD HAZARD MAP
SAMPLE LANDSLIDE HAZARD MAP
SAMPLE STORM SURGE HAZARD MAP
56
OUTPUTS
• Successfully finished and delivered around 5,300 maps to UNDP covering the 1810 barangays listed.
• All maps were printed in tarpaulins with corresponding CDs per barangay ready for distribution by the UNDP Team
