Hanoi - A 6.5-magnitude earthquake struck Mindoro island of the Philippines on June 15, according to the German Research Centre for Geosciences (GFZ).

Meanwhile, the US Geological Survey (USGS) said the earthquake had a magnitude of 6.2 and its focal depth was estimated at 125 km.

The Philippine seismology agency said it also recorded a 6.2-magnitude earthquake. It also warned of aftershocks and possible damage.

Witnesses said tremors could be felt in the capital city of Manila and adjacent provinces.

The Philippines lies along the "Pacific Ring of Fire" which is surrounded by numerous active faults and trenches on both sides of the archipelago, so it frequently records seismic activity.
