Solomon Islands: A magnitude-5.5 offshore earthquake occurs near the Santa Cruz Islands at around 01:33 Dec. 21

A magnitude-5.5 earthquake occurred near the Santa Cruz Islands in the Solomon Islands at around 01:33 Dec. 21. The epicenter was about 130 km (81 miles) south-southeast of Lata, Temotu Province. The tremor occurred at a depth of about 10 km (6 miles), and light shaking was probably felt throughout the Santa Cruz Islands and far northern Vanuatu. The earthquake was preceded by a magnitude-5.0 tremor at around 01:10 Dec. 21. 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. 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.
