A coastal uplift triggered by the magnitude 7.8 earthquake that struck Sarangani and nearby provinces has been confirmed along portions of the shoreline in Glan. Following reports from residents that sea levels remained unusually low after the quake, personnel from the Provincial Environment and Natural Resources Office, Cenro Glan, and the SBPS Protected Area Management Office conducted field assessments. They found extensive areas of exposed shoreline, coral reefs, and seagrass beds, particularly within the Pangyan Marine Sanctuary.
Confirmation by Authorities
On June 11, the Philippine Institute of Volcanology and Seismology and Mines and Geosciences Bureau Region 12 confirmed that the earthquake raised parts of the seabed by about two meters and extended the shoreline by approximately 200 meters.
Environmental Impact
Authorities said the uplift has left corals, seagrass, and marine organisms exposed, resulting in signs of die-off in some areas. The exposed marine life is at risk due to prolonged exposure to air and sunlight.
Upcoming Scientific Study
A joint scientific study involving the Department of Environment and Natural Resources (DENR), MGB-12, and local government units is scheduled on June 16 to further assess the phenomenon and its environmental impact. The study aims to understand the extent of the damage and plan mitigation measures.
