A Pacific tsunami warning issued following strong earthquakes off Vanuatu has been lifted, after only a tiny wave was generated.
The first quake with a magnitude of 7.8 was followed about an hour later by one of 7.1, the US Geological Survey said.
The first epicentre was 295km (180 miles) north-northwest of Vanuatu's largest island, Santo, at a depth of 35km (21.7 miles).
People had already begun to move to higher ground.
In Vanuatu residents evacuated low-lying areas and fled to higher ground. In New Caledonia, schools in coastal areas were evacuated.
More than 170 people died last week when a tsunami triggered by a quake hit Samoa, American Samoa and Tonga.
All three nations were initially included in a "tsunami watch" - a lower level of alert than a tsunami warning - but were later upgraded to the warning level, before the warnings were cancelled.
Earlier on Wednesday, a 6.7-magnitude quake struck off the Philippines, but no tsunami warning was issued.
Location of Vanuatu within the South PacificAccording to the United States Geological Survey (USGS), a magnitude 7.8 earthquake struck the Vanuatu region in the Pacific Ocean on Wednesday. The quake was followed by a large aftershock with a magnitude of 7.3.

So far there are no reports of damage or injuries.

Both of the quakes' epicenters were centered roughly 373 kilometres northwest of the Vanuatu city of Santu, at a depth of 33 kilometres.

Vanuatu was placed under a tsunami warning after the earthquake started, however, it has since been removed, as the tremors managed to produce only small waves.

The earthquake comes a week after another heavy tremor caused tsunamis in the South Pacific. That quake killed 170 people on the islands of Tonga, Samoa, and American Samoa.
