Reported Shaking and Intensity
Reported Intensity IV was recorded in Lingig, Surigao del Sur; Intensity III in Bislig City and Hinatuan, Surigao del Sur; and Intensity I in Baganga and Boston, Davao Oriental.

Damage and Casualty Update
PHIVOLCS says damage is not expected. This is the agency’s assessment, not confirmation from a completed damage survey. The bulletin does not provide verified casualty or damage figures.
AI-Assisted Content Disclosure:
The information below was generated with the assistance of artificial intelligence and is provided for general informational and educational purposes only. While every effort has been made to ensure accuracy and clarity, AI-generated content may contain errors, omissions, or interpretations that do not reflect the latest scientific findings or official guidance.
This content should not be considered a definitive or authoritative source for earthquake-related information. Readers are encouraged to verify important details with official agencies such as PHIVOLCS, the Office of Civil Defense (OCD), and other relevant government or scientific institutions before making decisions or taking action.
Always rely on official advisories during emergencies and disaster situations.
Why Did This Earthquake Happen?
PHIVOLCS identifies the event as tectonic. The bulletin does not attribute it to a specific named fault or trench, so no such association is asserted here.
Is There a Tsunami Threat?
The examined earthquake bulletin does not state tsunami guidance. This is neither a tsunami warning nor a separate all-clear. Coastal residents should follow any official PHIVOLCS tsunami advisories and local government instructions.
Could Aftershocks Occur?
Yes. PHIVOLCS states that aftershocks are expected. Residents should remain alert to further shaking and verify that subsequent bulletins refer to the same event.
Could This Trigger Other Earthquakes?
The bulletin does not establish that this event triggered another earthquake or was triggered by the earlier event. A sequence relationship should not be assumed without official scientific confirmation.
Safety Advice
During strong shaking, Drop, Cover and Hold On. After shaking stops, check for hazards and follow local disaster authority advisories. Coastal residents should also monitor official tsunami advisories when relevant.
If you felt the earthquake:
- Remain alert and monitor PHIVOLCS for any subsequent earthquake bulletins and local government safety instructions.
- Stay away from visibly damaged buildings and structures. If you are in a high-rise, use a controlled evacuation rather than rushing into stairwells; see High-Rise Earthquake Evacuation, Part 2: Thirty Floors Down to Safety.
- Check your home for hazards such as gas leaks or damaged electrical wiring. Visit our blog, Ideas to Secure Your House Against Earthquakes: Simple Steps for Safety in the Philippines for ideas on securing your house.
- Monitor only official information from PHIVOLCS and local disaster authorities.
- Avoid sharing unverified information on social media.
- Remember to Drop, Cover, and Hold On if another strong earthquake occurs. If you are in a high-rise or workplace setting, review WVF’s High-Rise Earthquake Evacuation before deciding when and how to move after the shaking stops.
