Papua New Guinea: Magnitude-5.3 offshore earthquake occurs in Vitiaz Strait off northeastern Morobe Province at around 14:19 May 23

A magnitude-5.3 earthquake occurred in the Vitiaz Strait off northeastern Morobe Province at around 14:19 May 23. The epicenter was about 39 km (24 miles) north-northwest of Finschhafen. The tremor occurred at a depth of about 102 km (63 miles), and light shaking was probably felt throughout Morobe, eastern Eastern Highlands, southeastern Madang, and western West New Britain provinces. There have been no initial reports of damage or casualties; however, significant damage is unlikely. It could take several hours until authorities can conduct comprehensive damage assessments, especially in remote areas. 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.
