PNG: Magnitude-5.7 offshore earthquake occurs off East New Britain Province at around 23:52 Dec. 9

Event

A magnitude-5.7 offshore earthquake occurred off the northeast coast of East New Britain Province at around 23:52 Dec. 9. The epicenter was about 76 km (47 miles) south of Kokopo. The tremor occurred at a depth of about 35 km (22 miles), and moderate-to-light shaking was probably felt throughout East New Britain Province, as well as eastern parts of West New Britain and much of New Ireland Province. 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. The event has not prompted any tsunami advisories.

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

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.
