Philippines: Magnitude-7.0 earthquake strikes northern Luzon, July 27 /update 1

Event

A magnitude-7.0 earthquake occurred in Abra Province, Cordillera Administrative Region at around 08:43 PST July 27. The epicenter was about 11 km (7 miles) east-southeast of Dolores. The tremor occurred at a depth of about 10 km (6 miles), and very strong shaking was likely felt throughout Abra Province, while strong to moderate shaking was probably felt throughout northern and central Cordillera Administrative Region, northern Cordillera Administrative Region, and western Cagayan Valley. Moderate to light shaking was probably felt throughout the rest of northern Luzon. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is possible. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. A magnitude-4.9 aftershock was recorded 09:29 July 27. Additional moderate to light aftershocks are likely over the coming days.

Reports indicate that authorities halted Manila City's metro rail systems for inspections in case of damage. The senate building in Manila was also evacuated. Officials may temporarily shut down additional transportation infrastructure in the tremor zone to check for damage. Minor disruptions could occur during shutdowns, but service will likely resume quickly if no damage is found. Utility outages are possible, particularly near the earthquake's epicenter.

Advice

Plan accordingly for aftershocks. Consider vacating multistory buildings if operating in affected areas until authorities confirm their structural integrity. Allow additional time for air and road travel, as aftershocks may prompt brief disruptions. Seek updated information on road conditions before driving in hilly areas in the affected region due to potential landslides.
