New Caledonia: Magnitude-5.1 offshore earthquake occurs east of the Loyalty Islands at around 20:46 NCT July 21

Event

A magnitude-5.1 offshore earthquake occurred in the South Pacific Ocean east of New Caledonia's Loyalty Islands at around 20:46 NCT July 21. The epicenter was about 149 km (93 miles) east of Tadine, New Caledonia. The tremor occurred at a depth of about 25 km (16 miles), and light shaking was probably felt throughout much of the Loyalty Islands, Ile des Pins, and far southern Grande Terre Island in New Caledonia and the far southern islands of Vanuatu. 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.
