Vanuatu: A magnitude-5.4 offshore earthquake occurs in the Coral Sea at around 03:19 Sept. 23
A magnitude-5.4 offshore earthquake occurs north of Vanuatu at around 03:19 Sept. 23. No immediate reports of damage or injuries.
Event
A magnitude-5.4 earthquake occurred north of Vanuatu at around 03:19 Sept. 23. The epicenter was approximately 27 km (17 miles) west-northwest of Port-Olry. The tremor occurred at a depth of about 40 km (25 miles), and weak-to-light shaking was probably felt throughout much of Vanuatu. There have been no initial reports of damage or casualties as a result of the earthquake; 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.
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.
