Manila, - A magnitude 6.7 earthquake shook the southern Philippines on Friday. There were no immediate reports of casualties.
US Geological Survey said the quake struck off Sarangani province on the main southern island of Mindanao at a depth of 78 kilometers.
No tsunami threat was issued after the quake, but local authorities warned of potential damage.
The Philippines is witnessing increased volcanic and seismic activity due to its location on the Pacific Ocean's Ring of Fire, where tectonic plates intersect.
One of the strongest earthquakes struck the island of Luzon in the north of the Philippines in July 1990, with a magnitude of 7.8 on the Richter scale, killing more than 2,400 people.
