A magnitude 6.5 tectonic earthquake shook wide areas of Mindanao and parts of the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) on the evening of Friday, June 26, 2026, with shaking felt as far as Zamboanga City, Basilan, Sulu, and parts of Bukidnon. The Philippine Institute of Volcanology and Seismology of the Department of Science and Technology (PHIVOLCS-DOST) reported no damage is expected, but warned that aftershocks are likely.
What Happened and Where
The earthquake struck at 7:34:35 PM Philippine Standard Time (PHT) on June 26, 2026. Its epicenter was located 70 kilometers south-southwest of Balut Island in the Municipality of Sarangani, Davao Occidental, at coordinates 4.82°N, 125.21°E. The quake originated at a depth of 38 kilometers and was classified by PHIVOLCS-DOST as tectonic in origin — meaning it was caused by natural movement along fault structures in the earth's crust.
This bulletin is Earthquake Information No. 3, issued by PHIVOLCS-DOST on June 27, 2026, at 11:50 AM PHT. An epicentral map accompanies the official bulletin.
