At least eight people were killed and four injured, the Philippine civil defence office said, after a magnitude 7.8 earthquake struck one of the country's southern islands.
There were no immediate details about the deaths.
Tsunami warnings were triggered after the quake struck off the southern Philippine island of Mindanao on Monday.
The Pacific Tsunami Warning Centre said tsunami waves up to three metres were possible on some coasts of the Philippines. Waves of almost a metre were possible on some coasts of Indonesia and Malaysia.
Philippine President Ferdinand Marcos Jr said authorities were moving fast to coordinate disaster response. "The national government is moving and we will not leave Mindanao behind," he said in a statement.
Tsunami warnings were also issued in neighbouring Indonesia, but were later removed.
The Philippines and Indonesia experience hundreds of earthquakes each year and sit on tectonically complex parts of the Pacific Ring of Fire, a seismically active belt stretching from South America to the Russian Far East.
