PNG: A magnitude-5.3 offshore earthquake occurs in the Bismarck Sea at around 18:40 June 17

A magnitude-5.3 earthquake occurred in the Bismarck Sea at around 18:40 June 17. The epicenter was about 229 km (142 miles) southeast of Lorengau, Manus Province. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt throughout parts of eastern Manus, far northwestern New Ireland, and far northern West New Britain provinces. 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.
