A magnitude 6.4 earthquake has occurred in the Santa Cruz islands in the Pacific but there is no immediate warning of a tsunami.
The US Geological Survey says the quake struck at a shallow depth of 10km about 355km north of Luganville, part of the Vanuatu archipelago, at 8.37pm on Monday (local time).
It followed a series of large quakes last week that triggered a region-wide tsunami alert.
A tsunami hit Samoa, American Samoa and Tonga after a magnitude 8.0 earthquake on 29 September, wiping out villages and resorts. At least 184 people were killed.
