A 5.7 quake shook parts of the southern Philippines late on Saturday, injuring at least 10 people and causing minor damage to structures, officials said.
The Philippine Institute of Volcanology and Seismology said Sunday the quake struck near the town of Carmen on Mindanao island, shaking people awake and causing panic.
It was felt in varying intensities across eight nearby towns and cities, according to the regional civil defence office.
At least 10 people were hurt due to falling debris, while 46 houses made from light materials in remote rural areas were partially damaged, the civil defence office said.
Walls in five school buildings were found to have cracked but were deemed stable for when students return to school on Monday after the summer holiday, regional civil defence officer Carlo Daminay said.
The Philippines sits on the Pacific Ring of Fire, where continental plates collide, causing frequent seismic and volcanic activity.
