Philippines: A magnitude-5.4 earthquake occurs near Batan Islands region at around 09:43 PHT Aug. 13

Event

A magnitude-5.4 earthquake occurred in the South China Sea, near the Batan Islands region of the Philippines at around 09:43 PHT Aug. 13. The epicenter was about 42 km (26 miles) southwest of Basco, Batanes Province. The tremor occurred at a depth of about 48 km (30 miles), and moderate-to-light shaking was probably felt near the epicenter, as well as light shaking throughout northern parts of Cagayan Valley region, as well as southernmost parts of Taiwan. There have been no initial reports of damage or casualties as a result of the earthquake; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Light aftershocks are likely over the coming days.

Officials may temporarily shut down 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

Out of an abundance of caution, consider vacating multistory buildings where shaking occurred until authorities confirm their structural integrity. Monitor and plan for aftershocks.
