How Sorsogon prepared for Typhoon Glenda

When Typhoon Glenda (internationally known as Rammasun) made landfall in the Philippines last July 2014, vulnerable communities in Sorsogon were prepared for it as they had disaster preparedness and response initiatives in place since 2011, thanks to the WFP and USAID/OFDA.

Case Study

How Sorsogon Prepared for Typhoon Glenda

HFA Priority

HFA Priority 2: Identify, assess and monitor disaster risks and enhance early warning.

HFA Priority 5: Disaster preparedness: Strengthen disaster preparedness for effective response at all levels.


Sorsogon is a province in the Bicol region of the Philippines which ranks fourth nationwide in terms of typhoon risk, and sixth in terms of volcanic risk. Glenda was just the seventh typhoon to enter the Philippines area on July 2014. It made its first landfall in Albay province at around 1700 hours with maximum sustained winds of 150 kilometres per hour.


Municipality of Juban, Province of Sorsogon, Philippines.

How the problem was addressed?

The municipal local government unit (LGU) produced and circulated hazard maps, which identified the barangays (communities) most vulnerable to storm surges.

The Municipal Disaster Risk Reduction Management Office (MDRRMO) provided training on GIS and hazard maps.

Challenge: coming up with barangay level cost effective hazard maps;

Solution: a Free and Open Source Geographic Information System (QGIS)

Lesson Learned

Investment in preparedness saves lives – zero casualty in Juban during Typhoon Glenda.


Pre-emptive evacuation of the identified vulnerable communities along the path of Typhoon Glenda

Measuring success

Hazard maps which identified vulnerabilities and most susceptible communities.

Evacuation plans based on contingency plans crafted by the municipality.

Number of casualties in the municipality from Typhoon Glenda.

Relevance to HFA

The municipal government was able to identify, assess and monitor disaster risks and enhance early warning

Did the HFA or the Making Cities Resilient Campaign play a role in enabling this initiative?



If yes, how?


HFA provided the impetus for enacting national legislation on DRR and an entry point for the intervention by United States Agency for International Development (USAID)/ Office of U.S. Foreign Disaster Assistance (OFDA) and the World Food Programme (WFP).

Potential for replication

Other LGU partners have participated in the GIS trainings resulting in many community-based hazard maps.

GIS training and community hazard maps are crosscutting components of the WFP Philippines programme on disaster preparedness and response/climate change adaptation.
