Late on Sunday evening, May 24, 2026, residents inside their homes in the City of Tandag, Surigao del Sur, felt the ground shake as a magnitude 5.0 tectonic earthquake struck the region at 9:19 PM Philippine Standard Time. The Philippine Institute of Volcanology and Seismology under the Department of Science and Technology (PHIVOLCS-DOST) promptly documented the event under Earthquake Information No. 2, providing the public with detailed technical data about the tremor's origin and impact.
Origin and Technical Details of the Earthquake
According to PHIVOLCS-DOST, the earthquake's epicenter was pinpointed at a location 57 kilometers north 66° east of Bayabas, Surigao del Sur, with geographic coordinates recorded at 9.18°N, 126.75°E. The tremor struck at precisely 9:19:01 PM Philippine Standard Time and originated at a relatively shallow depth of only 10 kilometers beneath the surface.
PHIVOLCS-DOST classified the earthquake as tectonic in nature, which means it was generated by the movement and shifting of geological fault lines deep within the earth's crust — a common cause of seismic activity in the Philippine archipelago — rather than being related to any form of volcanic activity. Shallow earthquakes, such as this one, are generally known to produce stronger ground shaking felt at the surface compared to deeper events of similar magnitude, making the classification and depth data particularly significant for affected communities.
Intensity Levels Reported Across Affected Areas
PHIVOLCS-DOST reported that the strongest shaking was experienced in the City of Tandag, Surigao del Sur, where the earthquake registered at Intensity III on the PHIVOLCS Earthquake Intensity Scale (PEIS). At this intensity level, many people indoors are able to feel the shaking, often describing it as similar to the vibration caused by a light truck passing close to a building. Hanging objects and lightweight items may be seen gently swaying during the tremor, though the sensation is generally not alarming enough to cause people to flee their homes.
Farther from the epicenter, in the town of Nabunturan located in Davao de Oro province, the earthquake registered only an instrumental Intensity I, as reported by PHIVOLCS-DOST. At this level, ground motion was captured and measured by sensitive seismological instruments, but the shaking was too faint to be noticed by people in the area. No reports of felt shaking were recorded from Nabunturan.
No Damage Expected, But Aftershocks Remain Possible
In its official bulletin, PHIVOLCS-DOST stated that no damage is anticipated as a result of this earthquake event. Given the magnitude, depth, and recorded intensity levels, the agency assessed that the tremor did not reach the threshold necessary to cause structural harm to buildings or infrastructure in the affected localities.
However, PHIVOLCS-DOST also noted that aftershocks remain a possibility following the main event. Residents in Tandag City and surrounding communities are advised to remain alert and to stay updated through official government channels. Aftershocks, while often weaker than the main quake, can occasionally cause alarm or minor structural stress, particularly in older or less reinforced buildings. The agency's advisory serves as a standard precautionary reminder for communities located in seismically active zones like Surigao del Sur.
Bulletin Issuance and Monitoring Information
The official earthquake bulletin covering this event was released by PHIVOLCS-DOST at 9:54 PM PHT on Sunday, May 24, 2026 — approximately 35 minutes after the earthquake was recorded. This relatively quick turnaround in bulletin release reflects the agency's ongoing effort to keep the public informed in near real-time following seismic events across the country.
PHIVOLCS-DOST designated this report as Earthquake Information No. 2 and indicated that it would serve as the final bulletin for this particular seismic event, unless new or additional data comes to light that warrants a follow-up issuance. An epicentral map showing the location of the earthquake's origin point is available through the agency's official bulletin publication.
For communities in and around Surigao del Sur, the Philippines' position along the Pacific Ring of Fire means seismic activity of varying magnitudes is a recurring reality. Residents are consistently encouraged by PHIVOLCS-DOST to practice earthquake preparedness, including identifying safe areas within their homes, preparing emergency kits, and familiarizing themselves with local disaster risk reduction protocols set by the Local Government Units (LGUs) and the National Disaster Risk Reduction and Management Council (NDRRMC).
How to Stay Informed
The public is encouraged to monitor real-time earthquake information and updates directly through the official website of PHIVOLCS-DOST at phivolcs.dost.gov.ph. The agency regularly publishes seismic bulletins and advisories covering earthquakes recorded across the Philippine archipelago, providing communities with timely and accurate data to support informed decision-making during and after seismic events.
Local government offices in Surigao del Sur and the NDRRMC are also available as points of contact for residents seeking guidance on disaster preparedness and emergency response procedures following earthquakes.
