The coconut-growing province of Quezon, south of the capital, was said to have borne the brunt of Category-3 Typhoon Rammasun.
More than 420,000 people were forced out of their homes and into evacuation centers, many in the eastern Bicol region where the eye of the typhoon made landfall.
Maximum sustained winds near Rammasun’s center were clocked at 93 mph, which toppled trees and power lines as well as tearing the roofs of homes around the capital.
The storm weakened to Category-1 force late Wednesday after it had passed across the full breadth of Luzon Island and moved over the South China Sea.
Forecasters predicted Rammasun, a Thai word for "Thunder God," would strike southern China and far northern Vietnam by the weekend.
Meteorologists predicted late Thursday that the storm could be at Category-4 intensity when it strikes China's island province of Hainan.
