Four days after a massive earthquake hit the island nation of Vanuatu, earthquakes continue to shake Pacific Island communities.

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 magnitude 6.1 earthquake rattled buildings on Vanuatu's main island early Sunday but did not appear to have caused major damage, just days after a massive, deadly quake wreaked havoc on the Pacific archipelago.

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.

At least 10 buildings in Port Vila suffered significant damage, while a nearby landslide was responsible for at least six deaths, the Vanuatu government said.

At least one person was killed after a powerful 7.3-magnitude earthquake struck the main island of Vanuatu in the South Pacific on Tuesday, triggering landslips, flattening buildings and cutting power and communications.
