The Philippine Institute of Volcanology and Seismology (Phivolcs) issued a tsunami warning following a magnitude 6.9 earthquake that struck Manay, Davao Oriental, at 7:12 p.m. on Friday, October 10. The quake, located 36 kilometers southeast offshore of Manay with a depth of 10 kilometers, came hours after a magnitude 7.4 temblor hit the same area earlier that morning. Residents in coastal areas of Davao Oriental, Surigao del Norte, and Surigao del Sur were strongly advised to evacuate to higher ground or move farther inland. Phivolcs forecasted the first tsunami waves, expected to exceed one meter above normal tides, to arrive between 7:12 p.m. and 9:12 p.m., warning that the waves could persist for hours. A tsunami alert was also issued after the morning earthquake but was lifted shortly after.
