PNG: Magnitude-5.6 offshore earthquake occurs in the Bismarck Sea off Madang Province at around 19:09 June 14

Event

A magnitude-5.6 offshore earthquake occurred in the Bismarck Sea near Long Island at around 19:09 June 14. The epicenter was about 135 km (83 miles) north of Lae. The tremor occurred at a depth of about 178 km (111 miles), and light shaking was probably felt throughout much of Madang, Morobe, and Eastern Highlands provinces, as well as eastern Chimbu and western 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.

Advice

Out of an abundance of caution, consider vacating multistory buildings where shaking occurred until authorities confirm their structural integrity. Monitor and plan for aftershocks.
