MANDAUE CITY, Cebu — Long stretches of shoreline are now visible, while coral reef and seagrass beds have been exposed at the Pangyan Marine Sanctuary in Barangay Pangyan, Glan, Sarangani Province, following the magnitude 7.8 earthquake that struck parts of Mindanao on June 8.

This was confirmed through an aerial survey and ground validation conducted on June 11 by the Department of Science and Technology–Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) and the Department of Environment and Natural Resources–Mines and Geosciences Bureau (DENR-MGB) in Soccsksargen (Region XII).
