Papua New Guinea: Magnitude-6.3 offshore earthquake strikes in the Bismark Sea, north of Madang, at 1545 PGT Feb. 7

Event

A magnitude-6.3 earthquake occurred in the Bismarck Sea at around 1545 Feb. 7. The epicenter was about 215 km (133 miles) north of Madang, Madang Province. The tremor occurred at a depth of about 10 km (6 miles) and likely triggered strong shaking near the epicenter. Moderate shaking probably occurred in parts of northeastern New Guinea Island. There have been no initial reports of damage or casualties; however, it could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. Aftershocks are possible. Officials did not issue a tsunami warning.

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 they do not find damage. Utility outages are possible, particularly in coastal areas near the earthquake's epicenter.

Advice

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.
