MANILA - A 5.5-MAGNITUDE earthquake struck the southern Philippines early on Friday, the US Geological Survey said, but there were no immediate reports of casualties or damage.
The undersea quake struck at 2.12am around 136 kilometres south-west of the city of General Santos on Mindanao island, the USGS said.
The quake's epicentre was located at a depth of 429km.
A strong 6.2-magnitude earthquake hit the area on Thursday, sparking scenes of panic among residents but without causing any major damage, officials said.
The archipelago nation, made up of more than 7,000 islands, sits on the Pacific 'Ring of Fire' where continental plates collide, causing frequent seismic and volcanic activity. -- AFP
