A 6.8-magnitude earthquake has struck a South Pacific island chain north of New Zealand, in the second powerful quake there in days.

Today’s quake struck 100 miles south-east of Raoul Island, the only inhabited island in the Kermadec chain.

The U.S. Geological Survey said it had a shallow depth of just over six miles and there were no immediate reports of casualties.

Reassuring the public, New Zealand’s civil defence ministry said there was no danger of a tsunami hitting the country.
