A tsunami warning has been issued for the Philippines, Indonesia and Palau after a 7.6-magnitude earthquake offshore.
The quake had a depth of 33km (20 miles) and struck at 20:47 local time (12:47 GMT), the US Geological Survey said. It was located off the Philippines island of Samar.
Unconfirmed reports said it destroyed roads and bridges in the Philippines.
It is not yet known if a tsunami has actually been generated.
Warnings were also initially issued for Taiwan, Japan, Papua New Guinea, Guam, the Northern Mariana Islands and Yap, but were later lifted.
The epicentre of the quake was 146km from the town of Guiuan, on the southern tip of Samar.
"Strong earthquake here in Taft, Eastern Samar! And it lasted very long too," Reuters news agency quoted a local congressman, Ben Evardone, as saying in a text message.
Philippine officials said residents on the eastern coast of the island were being advised to move to higher ground.
The predicted tsunami landfall times appear to have passed without immediate reports of damage, but officials say potential waves could hit later.
