A magnitude-6.1 earthquake rattled buildings on Vanuatu's main island early Sunday (Dec 22) but did not appear to have caused major damage, five days after a more powerful quake wreaked havoc and killed 12 people.

Commercial flights had been set to resume on Sunday before a new earthquake struck the island nation. Aid efforts remained strained because of the difficulty accessing the Pacific island.

The quake briefly prompted a tsunami alert for parts of Vanuatu, according to the U.S. Tsunami Warning System, which is part of the National Weather Service. As of 2:14 p.m. local time, U.S. officials said the threat had passed.

A 7.3 magnitude earthquake hit Vanuatu on Tuesday, December 17 that has destroyed buildings across the capital of Port Vila with 14 confirmed deaths and more expected as recovery efforts get underway.
