A 6.4-magnitude earthquake has struck the southern Philippines, but there were no immediate reports of damages or injuries.

The epicentre of the quake mid-morning on Sunday was southeast of Jose Abad Santos town in Davao Occidental province, 1096km south of Manila, according to the Philippine Institute of Volcanology and Seismology.

Nearby General Santos City felt the strongest intensity where it was registered as a magnitude 4, it added.

The institute said several aftershocks have already been recorded.

The Philippines is located on the Pacific Ring of Fire, where about 90 per cent of the world's earthquakes strike.

The last major quake to hit the country was a 7.1-magnitude tremor that killed more than 220 people in the central Philippines in October 2013.

In July 1990, more than 2400 people were killed on the northern island of Luzon in a magnitude-7.8 quake, one of the strongest tremors ever to hit the country.
