Large waves are washing ashore in Tonga after another violent volcanic eruption hit the island nation - and Government officials issued a second tsunami warning in two days.

The tsunami alert follows yesterday's eruption of Hunga Tonga-Hunga Haʻapai, an underwater volcano, sending ash, steam and gas up to 17km into the air.

Volcanic ash is currently raining down on Nuku'alofa, Tonga's capital.

The police and local authorities have advised for all residents to move to higher ground.

A tsunami alert has been issued for Fiji and American Samoa. Residents of low-lying areas were urged to move to higher ground.

New Zealand's National Emergency Management Agency sent a National Advisory alert to notify of tsunami activity.

"We expect New Zealand coastal areas on the north and east coast of the North Island and the Chatham Islands to experience strong and unusual currents and unpredictable surges at the shore," it tweeted.

RNZ says there are reports of sirens ringing across Nukualofa and police are asking people to move to higher ground.

There are also reports on social media of the explosion being heard in Fiji - and as far away as Samoa.

The Tonga Meteorological Services posted to Facebook noting a warning is in place for the entire island.

Locals have been posting online, including one who wrote: "A volcanic explosion just erupted and people have evacuated to higher ground now from possible tsunami waves also ash shards are falling and now the ash clouds are covering the island of Tongatapu.

"We live in Kolomotu'a near the ocean so we have left already and we are in our cars heading out but traffic on every road. Please pray for us as a family and safety."

Anthony Browne is in Fiji and told the Herald the eruption is still being heard and felt as far away as Nadi, Fiji.

"For the last hour there have been continuous explosive sounds with continuous rumbling, windows rattling and doors rattling."

Spectacular footage posted on Twitter shows waves flowing into the streets from a beach in Tonga.

The Hunga Tonga-Hunga Haʻapai volcano is located about 30km south-east of Fonuafo'ou island in Tonga. It had been active from December 20, 2021, but was declared dormant on January 11.
On Friday, several Tongan geologists went to observe the Hunga Tonga-Hunga Haʻapai volcano.

Taaniela Kula, Deputy Secretary, Ministry of Lands & Natural Resources – who was in charge of the group – told local media outlet Matangi Tonga: "Yesterday there were massive explosives, thundering lightning within two miles away, we observed and recorded.

"Big day yesterday indeed!. It was great getting out there during the volcano's peak hours. It's a geologist's dream to see actual geological events in process."

The ongoing plumes of debris from the volcano earlier saw a halt of flights in Tonga.

As of yesterday, the maximum tsunami wave had been recorded in Nuku'alofa tide gauge at 12:30pm and was about 30cm above sea level.

RNZ reported the tsunami marine warning issued for all of Tonga waters, following the violent eruptions of underwater volcano Hunga-Tonga-Hunga-Ha'apai yesterday, lifted around midday today.
