MANILA (UPDATED) - At least 5 people were killed and dozens were hurt after a 6.1-magnitude earthquake jolted Zambales, Pampanga, Metro Manila, and parts of Luzon late Monday afternoon.
Pampanga Governor Lilia Pineda said at least 5 people died in her province, including a woman and her grandchild who were crushed to death in Lubao town.
She warned the death toll could go up as rescuers hunt for survivors after a supermarket in Porac town collapsed.
"We believe there are still people trapped in the four-storey building," Pineda said. "Our rescuers are telling us there are people in there shouting, begging to be rescued."
Pineda will declare a state of calamity in the province on Tuesday due to the massive damage caused by the tremor.
For Porac Mayor Condralito Dela Cruz, the ground moved like waves when he felt the earthquake.
"It was the strongest earthquake we've had. It was no joke," he told ABS-CBN News. "That's why we are shocked it (supermarket) gave way because it was still new."
Public Works Secretary Mark Villar said Central Luzon sustained heavy damage from the tremor, which centered in Castillejos, Zambales.
These include the Clark International Airport, bridges and old churches in Pampanga and Bataan, and the Dinalupihan-Pampanga Boundary Arc.
As of 8:30 p.m., some 102 people were reported injured while 31 remain missing in the region.
Thousands of travelers were also stranded after aviation authorities shut down the Clark International Airport.
