A 6.9 magnitude earthquake has hit 109km south of Sola in Vanuatu, the US Geological survey has said.
The quake was centred 109km west-southwest of Sola, and 460km northwest of Vanuatu's capital, Port Vila, at a depth of 33.7km.
Shadrack Welegtabit, director of Vanuatu's National Disaster Management Office, said officials had not received any reports of damage or injuries, and the shake was not felt in the capital.
Aftershocks are expected, but tsunami warnings have not been issued to the Pacific region.
This is the second strong quake to rattle Vanuatu this week. A quake of the same magnitude hit on Sunday, with no damage reported.
