The Mines and Geosciences Bureau Regional Office No. VIII completed the conduct of Vulnerability Risk Assessment (VRA) for its target municipalities in Northern Samar this year. The assessment started on February 2020 and was completed on November 2020.

The municipalities covered by the VRA in Northern Samar were the following: \Allen, Bobon, Catubig, Lavezares, Mondragon, Pambujan, Rosario and San Roque.

In line with the government’s mandate to reduce the adverse impacts of natural

geohazards, the Mines and Geosciences Bureau (MGB) implemented the National Geohazards Assessment and Mapping Program (NGAMP) which functioned as the department’s frontline activity for assessing the susceptibility of local communities to rain-induced landslides and floods. 

With the completion of the NGAMP, the Vulnerability and Risk Assessment (VRA)/ Exposure Mapping was conceptualized as a continuing collaborative effort by MGB, Local Government Units (LGUs) and other concerned government agencies to address the adverse effects of geohazards. The VRA/Exposure Mapping activity of the MGB assesses and quantifies the vulnerability of cities and municipalities based on their exposure to natural hazards. The overall vulnerability of the city or municipality depends on the degree of exposure and sensitivity with regards to the capability of the system to adapt and r

The Vulnerability and Risk Assessment Project intends to develop geohazard risk maps with accompanying reports by evaluating the existing vulnerability conditions in the local scene that could potentially harm various elements such as people and infrastructures.

“The assessment is important in providing technical information to the LGUs for the updating and modification of their Comprehensive Land Use Plan (CLUP) as well as project development, disaster preparedness, management, and mitigation programs,” explained RD Leo Van Juguan.

He added that the VRA is a critical input to the regional, provincial and local disaster preparedness, management and mitigation plans and land-use plans, which should reduce the impacts of the flooding and rain-induced landslides.

The said assessment includes the issuance of geohazard advisories to barangays and updating of the 1:10,000 scale geohazard maps and producing risk exposure maps for the different elements at risk (population, built-up areas and road networks). The resulting maps can help concerned local government officials in formulating a viable Comprehensive Land Use Plan (CLUP) and enhanced Disaster Risk Reduction and Management (DRRM) plan.
