A 5.2-magnitude earthquake, according to the US Geological Survey’s (USGS) initial estimate, has shaken buildings in the capital of the Philippines, with authorities warning of the risk of damage and aftershocks.

The quake, with a shallow focal depth, was centered about 100 kilometers south of the capital Manila and was registered at 08:24 (local time; 03:24 Greece time), forcing many workers out of office buildings and into the streets.

“So far, everything is going well. There are no casualties,” said Rafael Cuevas, a disaster management official in Calaca town, nearly 100 kilometers south of Manila, in Batangas province.

“We felt a strong earthquake that lasted less than ten seconds,” he added.

Earthquakes are recorded daily in the Philippines, a country on the “ring of fire” of the Pacific Ocean, a zone with intense seismic and volcanic activity.
