6.6-Magnitude Earthquake Jolts Southern Philippines

A strong earthquake with a magnitude of 6.6 jolted Mindanao in the southern Philippines on Friday evening, June 26, 2026. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported the quake occurred at 07:34 PM local time.

The strongest shaking registered intensity V on the Modified Mercalli Intensity (MMI) scale in Kiamba, Sarangani, where tremors were strong enough to move or topple objects inside buildings. The earthquake's epicenter was located offshore, approximately 90 kilometers southwest of Balut Island in Sarangani, Davao Occidental, according to PHIVOLCS. Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG) recorded the event as a magnitude 6.8 earthquake, placing its epicenter around 196 kilometers northwest of Tahuna in the Sangihe Islands.

Fortunately, the offshore location meant no tsunami warning was issued. This event follows a devastating magnitude 7.8 earthquake that struck Mindanao on June 8, resulting in 81 fatalities and over 1,000 injuries. That earlier quake also generated a small tsunami that reached parts of Indonesia. The tremor from the latest earthquake was felt in Indonesia's Talaud Islands, North Sulawesi, at intensity III MMI, described as noticeable indoors and similar to the vibration of a passing truck.
