A strong earthquake of magnitude 6.3 hit Mindanao, the second largest island in the Philippines, on Sunday, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported. The tremor was recorded at 12:22 p.m. (local time) at a depth of 15 km in the Davao del Sur province located in the Davao Region in Mindanao.
The GFZ German Research Centre for Geosciences earlier reported a 6.0-magnitude quake at a depth of 10 km.
There are no immediate reports of any casualties caused by the quake, however, Phivolcs warned that aftershocks and damages are expected.
The Philippines is located in the so-called Ring of Fire, a vast Pacific Ocean region where many earthquakes and volcanic eruptions occur.
The archipelago lies along the border between the Philippine Sea Plate and the Eurasian Plate, which are colliding, increasing the seismological activity in the area.
