Powerful 7.6-Magnitude Earthquake Strikes Off Southern Philippines, Triggers Tsunami Warning

A powerful offshore earthquake with a preliminary magnitude of 7.6 struck near the southern Philippines early Friday morning, sparking panic among residents, cutting off power in several areas, and prompting urgent tsunami evacuation orders across coastal communities.

According to the Associated Press (AP), the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the tremor was tectonic in origin, caused by movement along a shallow fault line about 10 kilometres (6 miles) deep. The epicentre was recorded approximately 62 kilometres (38 miles) southeast of Manay town in Davao Oriental province, facing the Pacific Ocean.

Officials warned that the shallow depth and offshore location of the quake could produce strong aftershocks and potential structural damage, particularly in coastal and mountainous areas.

Panic and Power Outages Reported

Residents across Davao Oriental and neighbouring provinces described intense shaking that lasted several seconds, sending people rushing out of homes, offices, and classrooms. Power outages were immediately reported in several towns following the tremor.

In Davao City, the region’s largest urban centre with a population of about 5.4 million, classes were suspended, and students were evacuated from school buildings as a safety precaution. Authorities urged residents to stay calm but remain vigilant in anticipation of aftershocks.

Local disaster management offices have been placed on high alert, with emergency teams deployed to assess damage and assist with evacuation efforts.

Tsunami Warnings Issued

The Pacific Tsunami Warning Center (PTWC) in Honolulu issued an alert stating that hazardous tsunami waves were possible within 300 kilometres (186 miles) of the earthquake’s epicentre.

According to the advisory, waves could reach up to 3 metres (10 feet) above normal tide levels along parts of the Philippine coastline, particularly in eastern Mindanao. Smaller waves were also expected along some coasts of Indonesia and Palau.

PHIVOLCS promptly ordered residents in coastal villages of Davao Oriental, Surigao del Sur, and other eastern provinces to move to higher ground. Local authorities activated public warning systems and used sirens, radio, and social media alerts to warn of possible incoming waves.

Authorities Brace for Aftershocks

PHIVOLCS Director Dr. Teresito Bacolcol confirmed that aftershocks were expected in the coming hours and days, warning residents to remain cautious.

“We are closely monitoring the situation. Based on our analysis, this earthquake was shallow and could cause significant ground shaking. We advise people to stay alert, especially in areas near slopes and riverbanks, due to possible landslides or ground fissures,” Bacolcol said.

Emergency services have also been instructed to inspect bridges, roads, and coastal infrastructure for potential damage. As of the latest reports, no immediate casualties have been confirmed, but assessments are ongoing.

Regional Response and Safety Measures

Local government units across Mindanao and parts of the Visayas have activated disaster response protocols, setting up temporary shelters for evacuees and ensuring that hospitals and emergency responders remain operational despite power interruptions.

Philippine Coast Guard units have been dispatched to monitor sea conditions, while airlines and port authorities are reviewing possible disruptions to transport services in the affected areas.

President Ferdinand Marcos Jr. has been briefed on the situation, and the National Disaster Risk Reduction and Management Council (NDRRMC) said it is coordinating with regional offices to ensure quick relief and response operations.

A Region Prone to Seismic Activity

The Philippines sits on the Pacific Ring of Fire, a major area in the Pacific Ocean basin where many of the world’s earthquakes and volcanic eruptions occur. The country experiences frequent seismic activity due to the presence of multiple active fault lines and subduction zones.

In December 2023, a magnitude 7.6 earthquake struck the same region, killing at least two people and injuring several others, underscoring the area’s vulnerability to powerful undersea tremors.

Tsunami Threat Being Monitored

As of Friday afternoon, PHIVOLCS and PTWC continued to monitor wave activity and assess whether the tsunami threat remains. Authorities warned residents not to return to coastal areas until an official “all clear” notice is issued.

Videos shared on social media showed residents in Mati City and other coastal communities running inland as emergency sirens blared. Officials said that even if a large tsunami does not materialize, dangerous sea level fluctuations and strong currents could still pose serious risks.

What Residents Are Advised to Do

Authorities have urged residents in affected regions to:

Stay away from beaches and low-lying coastal areas.
Move to higher ground immediately after strong shaking.
Avoid using elevators during or after the earthquake.
Be prepared for aftershocks and avoid damaged buildings.
Listen to official updates from PHIVOLCS, PTWC, and local government channels.

Emergency response teams continue to assess the extent of damage, and relief operations are being coordinated for communities that have been displaced.
