Five people are killed and dozens injured in the northern Philippines by a 7.0-magnitude earthquake.

According to authorities cited by the state-run Philippine News Agency (PNA), a strong earthquake that slammed the northern Philippines on Wednesday left at least five people dead and 64 others injured.

The Philippine Institute of Volcanology and Seismology (Phivolcs) advised the public to prepare for any aftershocks but stressed that because the earthquake was felt inland, no tsunami warning had been issued.

According to the US Geological Survey, the 7.0-magnitude earthquake struck northern Luzon, the country's most populous island, at 8:43 a.m. local time (8:43 p.m. ET) (USGS). The agency initially gave the earthquake a magnitude of 7.1 before lowering it to 7.0.

According to USGS, its epicenter was 10 kilometers (6.2 miles) beneath the surface, around 13 kilometers (8 miles) southeast of the small town of Dolores in the province of Abra. The capital, Manila, which is located more than 400 kilometers (approximately 250 miles) away, was also affected.
