A magnitude 6.1 earthquake struck off the coast of Sarangani Island in southern Mindanao, Philippines, at 07:07 a.m. local time on Saturday, June 28. The quake was felt across parts of Davao Occidental and nearby provinces but caused no reported damage or casualties, according to official sources.
The earthquake’s epicenter was located in the Philippine Sea, approximately 72 kilometers (44 miles) east-southeast of Sarangani, a small island municipality with a population of 7,596. It was also situated 87 kilometers (54 miles) southeast of Caburan, home to around 12,618 residents, and 116 kilometers (72 miles) east-southeast of Glan, a larger coastal town with a population of 24,256.
Shaking and Intensity
An estimated 1.26 million people experienced light shaking. PHIVOLCS (Philippine Institute of Volcanology and Seismology) noted Intensity IV to V in several communities, with shaking felt as far as mainland Davao Occidental.

The affected region features a mix of vulnerable and earthquake-resistant structures. Many homes are made of heavy wood or informal materials, which could be susceptible in stronger quakes.
Past earthquakes in this part of Mindanao have triggered landslides, especially following rainy periods. Although none have been reported from this event, local officials advised residents in hillside areas to stay alert.
Emergency Response
Local disaster officials and engineers are now inspecting bridges, schools, and other infrastructure. No major disruptions to transport or public services have been reported. Communities have been reminded to:
- Secure heavy objects at home
- Keep emergency supplies ready
- Practice “Drop, Cover, and Hold” drills
The Philippines sits on the Pacific Ring of Fire, a major zone of tectonic activity (which also includes volcanoes) . This region frequently experiences earthquakes due to the collision of the Philippine Sea Plate and surrounding fault systems.
While Saturday’s quake did not result in damage, it underscores the ongoing seismic threat faced by communities in the southern Philippines.
