Davao Oriental is no stranger to strong earthquakes. Between 1885 and 2023, at least six significant earthquakes, ranging from M7.1 to M8.3, have affected the region. The most recent damaging events were the MS7.1 and MS7.5 earthquakes in Manay, Davao Oriental, on May 17, 1992, which caused widespread damage to buildings and infrastructure and triggered a tsunami.
The region’s seismic activity is due to its location near the Philippine Trench and several segments of the Philippine Fault, including the East Compostela Valley, West Compostela Valley, and Mati Segments. Local inland and offshore faults also contribute to the earthquake potential.
Tsunami Warning
Following the quake, DOST-PHIVOLCS issued a Tsunami Warning for the coasts of Davao Oriental, Eastern Samar, Dinagat Islands, Leyte, Southern Leyte, Surigao del Norte, and Surigao del Sur. A 30-centimeter tsunami wave was recorded in Tandag City at 10:20 AM. The warning was lifted after four hours, but residents are urged to remain vigilant.
What to Expect
Aftershocks are expected to continue for days to weeks and may be felt in nearby provinces.
Other Hazards
In addition to ground shaking, potential hazards include:
- Earthquake-induced landslides and rock falls in mountainous areas.
- Liquefaction in low-lying, water-saturated areas.
- Potential inundation of seawater in coastal areas due to liquefaction and high tide.
- Sinkholes in areas with limestone bedrock.
Volcanic Activity?
The earthquake is tectonic in origin and not directly related to volcanic activity, though monitoring of nearby active volcanoes will continue.
Safety Measures
- Prepare for aftershocks: Practice “Drop, Cover, and Hold.”
- Inspect structures: Exercise caution around weakened buildings and coordinate with local engineering offices for inspection.
- Monitor slopes: Watch for tension cracks that may indicate landslide risk.
- Coastal awareness: Know the natural signs of a tsunami (strong earthquake, sudden rise or fall of seawater, roaring sound) and evacuate to higher ground if observed.
- Verify information: Rely only on official sources like DOST-PHIVOLCS for updates.
DOST-PHIVOLCS Response
DOST-PHIVOLCS is deploying a Quick Response Team (QRT) to Davao Oriental to assess the geologic impact and provide information to the public. The agency operates a network of 125 seismic stations across the Philippines, with the closest monitoring center in Davao City.

Double Quake Drama: Davao Oriental Shaken by Powerful Tremors
OCTOBER 10, 2025 9:43 AM: Davao Oriental, Philippines – A pair of strong earthquakes rattled the coast of Davao Oriental on Friday, October 10, sending shockwaves through the region. The first, a magnitude 7.4 tremor, struck at 9:43 am, followed hours later by a magnitude 6.8 quake at 7:12 pm.
First Earthquake
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) immediately issued warnings, anticipating damage and a series of aftershocks. Residents in coastal areas were particularly urged to stay vigilant.
“We expect aftershocks, some of which may be strong,” a PHIVOLCS spokesperson stated in a press conference held shortly after the initial quake. “It is crucial for the public to remain calm but alert and to follow safety guidelines.”
Second Earthquake
The second earthquake, while slightly weaker, added to the anxiety and disruption. People who had only just begun to assess the damage from the first quake were forced to seek safety once again.
Local authorities, along with national agencies, have initiated rapid response protocols. Teams are being dispatched to assess the extent of the damage and provide immediate assistance to affected communities.
“Our priority is to ensure the safety and well-being of our citizens,” said Davao Oriental Governor Niño Sotero L. Uy, Jr. in a statement. “We are coordinating with all relevant agencies to deliver aid and support to those who need it most.”
Aftershocks Rattle Davao Oriental: 476 Recorded Since Doublet Earthquake
The Philippine Institute of Volcanology and Seismology (Phivolcs) has reported that a staggering 476 aftershocks have been recorded as of 8:30 pm on Friday, October 10, following the doublet earthquake that struck off Davao Oriental.
Distinguishing Aftershocks
Phivolcs noted that due to the proximity of the magnitude 7.4 and magnitude 6.8 earthquakes, it is challenging to differentiate between the aftershocks of the two tremors. Prior to the second quake, 425 aftershocks had already been recorded from the initial magnitude 7.4 earthquake as of 7:11 pm.
Felt Aftershocks
Of the 476 aftershocks, at least 14 were strong enough to be felt as of 8:30 pm, causing further anxiety among residents.
Ongoing Monitoring
Phivolcs continues to monitor the situation closely and is urging the public to remain vigilant and prepared for further aftershocks.
“We advise the public to stay informed and follow safety guidelines,” said a Phivolcs spokesperson. “Aftershocks can occur at any time and may be strong enough to cause additional damage.”
Authorities are also continuing to assess the damage caused by the initial earthquakes and provide assistance to affected communities.
