As another year starts for the Mines and Geosciences Bureau Regional Office No. 8, the Geosciences Division have started to implement its calendar year 2019 projects.

In line with the Geological Risk Reduction and Resiliency Program, the division will be conducting year-round activities namely, the Vulnerability and Risk Assessment (VRA), Updating of 1:10,000 scale Geohazard Maps, Information, Education and Communication Campaign on Vulnerability and Risk Assessment (IEC-VRA), Groundwater Resource Assessment (GRA), Geologic Quadrangle Mapping and Karst Subsidence Hazard Assessment.

The Vulnerability and Risk Assessment (VRA) and Updating of 1:10,000 scale Geohazard Maps will be conducted to 11 municipalities in the region: six in Biliran province (Almeria, Biliran, Cabucgayan, Caibiran, Culaba and Kawayan), three in Eastern Samar (Balangiga, Giporlos and Lawaan), one in Northern Samar (Lao-ang) and one in Southern Leyte (Hinundayan). The VRA team have already been deployed to the municipalities of Biliran, Cabucgayan and Caibiran, all in the Province of Biliran.

For the Information, Education and Communication Campaign on Vulnerability and Risk Assessment (IEC-VRA), targets this year will focus on the municipalities where the VRA and updating of the 1:10,000 scale Geohazard Maps project was implemented in the year 2017. A total of 22 municipalities are slated for the one-day training-workshop, eight of which were VRA projects conducted by MGB Regions III, IX and X. The municipalities in Leyte covered by the IEC-VRA are Alangalang, Barugo, Calubian, Dagami, Hilongos, Hindang, Inopacan, Isabel, Leyte, Matag-ob, Merida, Palompon, Pastrana, San Isidro, San Miguel, Sta. Fe and Tabango. The remaining two municipalities are the islands of Tagapul-an and Zumarraga in Samar.

This year’s Groundwater Resource Assessment (GRA) will focus on 5 cities/municipalities in Samar (Calbayog City, Catbalogan City, Gandara, San Jorge and Sta. Margarita). As of writing, the team is already deployed in Catbalogan City, Samar and are conducting the fieldwork.

The Geologic Quadrangle Mapping project will cover 4 quadrangles in the region: Giporlos Quadrangle in Eastern Samar, Calbiga and Villareal Quadrangles in Samar, and Sta. Rita Quadrangle which is comprised of Leyte and a portion of Samar. The geologic mapping team have already been deployed to the Giporlos Quadrangle, which covers the municipalities of Balangiga, Giporlos, Lawaan and Quinapondan, Eastern Samar.

The Karst Subsidence Hazard Assessment, which focuses on sinkhole inventory and subsidence hazard assessment, will be conducted in Palompon, Leyte. The fieldwork is slated to be conducted on the month of May.
