UA violent 7.5 magnitude earthquake shook the Loyalty Islands and New Caledonia region in the Pacific on Wednesday, the American Geophysical Institute (USGS) announced. The earthquake triggered a tsunami alert, the Pacific Tsunami Warning Center said.
The USGS initially reported a magnitude of 7.9, which it then revised to 7.5 and then 7.7. The epicenter of the earthquake was located about 400 kilometers southeast of the Loyalty Islands archipelago, and about 430 kilometers from Vanuatu, according to the USGS.
One of the most intense seismic zones
New Caledonia is located in the southwest of the Pacific Ocean, about 1,500 km east of Australia. The region encompassing New Caledonia and neighboring Vanuatu is part of the Pacific Ring of Fire, one of the most intense areas of earthquake activity on the planet. The Australian plate bearing New Caledonia and the Loyalty Islands plunges under the Vanuatu arc creating the Vanuatu Trench.
