Pacific volcano: New Zealand sends flight to assess Tonga damage

New Zealand has sent a plane to Tonga to assess the damage after a huge volcanic eruption triggered a tsunami.

The eruption has covered the Pacific islands in ash, cut power and severed communications.

Up to 80,000 people there could be affected, the International Federation of Red Cross and Red Crescent Societies (IFRC) told the BBC.

New Zealand Prime Minister Jacinda Ardern said the tsunami had wreaked "significant damage".

No deaths have been reported so far.

Information remains scarce, however, and New Zealand and Australia are sending surveillance flights to assess the extent of the damage.

The New Zealand Defence Force tweeted that an aircraft had left to "assist in an initial impact assessment of the area and low-lying islands".

Katie Greenwood of the IFRC in Fiji said that help was urgently needed.

"We suspect there could be up to 80,000 people throughout Tonga affected by either the eruption itself or from the tsunami wave and inundation as a result of the eruption," she said.

"That was a shock to people, so we do hold some concern for those outer islands and we're very keen to hear from people."

The underwater volcano erupted on Saturday, sending a plume of ash into the sky and triggering warnings of 1.2m (4ft) waves reaching Tonga. The eruption was so loud it could be heard in New Zealand, some 2,383km (1,481 miles) from Tonga.
