A magnitude 6.3 earthquake has struck north of the archipelago of Vanuatu in the South Pacific, the United States Geological Survey (USGS) says.
There were no immediate reports of damages or casualties from the quake, which the agency said hit at a depth of 17km, about 475km north of the island of Santo, on Tuesday (local time).
That is between Vanuatu and the Solomon Islands.
There was no tsunami warning, advisory, watch or threat put into place.
The USGS had earlier placed the quake location east of the Solomon Islands provincial capital of Kira-Kira.
