PNG: A magnitude-5.4 offshore earthquake occurs northeast of the Admiralty Islands at around 20:43 Oct. 3

A magnitude-5.4 earthquake occurred in the South Pacific Ocean to the northeast of Papua New Guinea's Admiralty Islands at around 20:43 Oct. 3. The epicenter was about 173 km (107 miles) northeast of Lorengau, Manus Province. The tremor occurred at a depth of about 10 km (6 miles), and light-to-weak shaking was probably felt throughout much of Manus Province and far northern parts 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.
