The shallow 6.4-magnitude quake hit about 110km off Morong in Bataan province on Luzon island at 5.05am, with residents in nearby Manila woken by their buildings shaking.
Shallow quakes tend to do more damage than deep tremors, but the Philippine Institute of Volcanology and Seismology said damage was not expected.
“It’s strong and it’s shaking as if it’s dancing sideways,” said Lieutenant Aristotle Calayag, acting police chief of Lubang town in Occidental Mindoro, an island off Luzon.
“The people are used to earthquakes like this so they didn’t rush outside or panic,” he said.
Morong police chief Captain Michelle Gaziola told AFP the quake was “a bit strong but it was brief”.
“We’re okay. Most people are still asleep.”
