MANILA, Philippines (Updated) -- A magnitude 6.7 earthquake struck off the coast of Davao Oriental on Friday evening -- the strongest to hit the area since a magnitude 7.4 tremor rattled the region earlier in the day.

The quake was recorded at 7:12 p.m. and was felt across several parts of Mindanao, prompting a tsunami warning in nearby coastal provinces, according to state seismology agency PHIVOLCS.

The agency first reported the magnitude at 6.9 before revising it to 6.7.

Shaking felt across Mindanao. PHIVOLCS said Intensity IV shaking was felt in the cities of Davao and Bislig, and throughout Surigao del Sur. Instrumental intensities were also recorded in Magpet in Cotabato, Digos City in Davao Del Sur. Sta. Maria in Davao Occidental, Nabunturan in Davao de Oro, Gingoog City in Misamis Oriental, Malungon, Alabel in Sarangani, Tupi in South Cotabato, and Hinunangan in Southern Leyte.

Tsunami warning. Authorities are residents in coastal areas of Surigao del Sur, Davao Oriental, and Surigao del Norte to move to higher ground after PHIVOLCS issued a tsunami advisory.

The agency said forecast tsunami waves could arrive between 7:12 p.m. and 9:12 p.m.

Evacuation orders were issued in several towns as emergency response teams were deployed to monitor possible aftershocks and wave surges.

Casualties. At least one person was confirmed dead from the earlier magnitude 7.4 earthquake that struck the Davao region on Friday morning, causing widespread panic and power interruptions.

Authorities said damage assessments are ongoing, with reports of collapsed structures and minor landslides still being verified.
