A powerful 6.2-magnitude earthquake rocked the southern Philippine island of Mindanao on Saturday triggering panic, but there were no immediate reports of any damage or casualties.
The quake struck at 12:37 pm (0437 GMT), off the coast, about 30 kilometres (19 miles) northeast of the town of Sarangani, said the government seismology institute.
Residents said people rushed out of buildings in panic after the quake sent lighting fixtures swaying.
The government institute said it did not expect any damage or casualties and there was no risk of a tsunami.
The Philippines sits on the Pacific Ring of Fire - a belt around the Pacific Ocean dotted by active volcanoes and tectonic trenches.
A 7.6-magnitude quake hit the country's east coast in August last year, triggering a tsunami alert that forced tens of thousands to flee their homes and causing a landslide that killed one person.
