6.4-magnitude earthquake hits southern Philippines: USGS

A 6.4-magnitude tremor struck the southern Philippines on Tuesday, US geologists said, just a day after a deadly quake that rocked the country's north. The US Geological Survey said the earthquake hit near Tutubigan, which is hundreds of kilometres south of the quake that hit near Manila. USGS downgraded the magnitude of the fresh quake after initially recording it at 6.6.

On Monday, at least five people were killed when at least two buildings collpased after an earthquake measuring 6.4 on Richter Scale hit Philippines on Monday afternoon, reported AFP.

The quake struck at 5.11 pm local time at a shallow depth of 40 kilometres (25 miles), prompting the evacuation of central offices.  

The quake was centred on the town of Castillejos, about 100 kilometres (62 miles) northwest of Manila, local geologists said.

Scientists from the US Geological Survey logged its magnitude at 6.3, and said its epicentre was 40 kilometres (25 miles) below the Earth's surface.

According to reports, the 'Strong' earthquake shook buildings in Manila, the capital city. 

No casualty or loss of property has been reported as of now. 

News agency Reuters quoted a witness saying that offices were swaying in the business district of Makati City.

The Philippines is part of the Pacific "Ring of Fire", an arc of intense seismic activity that stretches from quake-prone Japan through Southeast Asia and across the Pacific basin.
