An earthquake with a preliminary magnitude of 7.0 struck Sunday morning off the southern tip of the South Pacific archipelago of Vanuatu, the U.S. Geological Survey said.
The quake struck about 75 miles (122 km) southeast of Isangel, the administrative capital of the island of Tanna, and 134 miles (217 km) northeast of New Caledonia's Loyalty Islands.
A tsunami alert has not been issued for the South Pacific or the U.S. western coast.
