The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reports that a magnitude 7.8 earthquake that struck parts of Mindanao on June 8 leads to coastal uplift in nearby areas of Sarangani and Davao Occidental. Multiple outlets cite PHIVOLCS findings that parts of the coastline shifted upward as a co-seismic effect, exposing seabeds and reshaping sections of shorelines. Reports also describe observable changes such as corals previously submerged becoming exposed above water. PHIVOLCS further notes that the uplift is accompanied by other ground impacts. An aerial and ground assessment conducted around June 11 finds evidence of landslides, tension cracks, road subsidence, and rockfalls in several locations, including areas in Glan and Jose Abad Santos in Davao Occidental, as well as parts of Sarangani and General Santos City. One PHIVOLCS statement says the coastal uplift does not require alarm, framing the deformation as expected effects of the earthquake rather than an indication of imminent new hazards.
