A magnitude 5.7 earthquake has jolted the central Philippines, sending workers out of their offices and causing cracks on a building's wall. There are no immediate reports of casualties.

The Philippine Institute of Volcanology and Seismology says the epicenter of Friday's earthquake was Antique province's Culasi municipality, 360 kilometers (224 miles) south of Manila.

John Paul Fallarme of the institute says field personnel reported cracks on the wall of a building in Culasi. Police say there are no immediate reports of damage in other areas.

Culasi police officer Richard Sombilon says officers and municipal employees ran out of their offices and gathered at a nearby plaza when the ground started shaking.

The Philippine archipelago lies in the Pacific "Ring of Fire," where earthquakes and volcanic activities are common.
