Tonga Meteorological Services said a tsunami alert was in effect for the whole of Tonga, and data from the Pacific Tsunami Warning Center showed that 80 cm waves had been detected.

The Bureau of Meteorology in Australia said a 1.2-meter-long tsunami wave had been observed in Nuku’alofa, Tonga’s capital.

Authorities in nearby Fiji and Samoa also issued warnings, telling people to avoid the shoreline due to strong currents and dangerous waves.

The Japanese Meteorological Agency said there may be a slight swelling of the water along the Japanese shores, but it is not expected to cause any damage.

That Islands business the news site reported that a convoy of police and military troops evacuated Tonga’s King Tupou VI from his palace near the coast. He was among the many inhabitants who set course for higher ground.

The eruption of Hunga Tonga-Hunga Ha’apai volcano was the latest in a series of spectacular eruptions.

A Twitter user identified as Dr. Faka’iloatonga Taumoefolau posted a video showing waves crashing ashore.

“Can literally hear the volcanic eruption, it sounds pretty violent,” he wrote, adding in a later post: “Raining ash and small pebbles, darkness covers the sky.”

The site said satellite images showed a 5km wide cloud of ash, steam and gas rising into the air to about 20km.

Local media on the island chain reported a downpour of ash, flooding of properties and disruption of telephone and power connections.

There were no immediate reports of injuries or the extent of the damage because all internet connection with Tonga was lost around 6.40pm local time, said Doug Madory, director of internet analysis for network intelligence firm Kentik.

The volcano is located about 64 km north of the capital Nuku’alofa.

Back in late 2014 and early 2015, a series of eruptions in the area created a small new island and disrupted international flights to the Pacific archipelago for several days.

Tonga is home to about 105,000 people.

A spokesman for the Australian government said initial assessments were under way and that the Foreign Office was working to ensure that Australians in Tonga were safe and held accountable.

“Tonga is part of our Pacific family and our thoughts go out to the entire community that is dealing with the impact of the volcanic eruption and tsunami,” the spokesman said in a statement.

“The Prime Minister and Foreign Minister are monitoring the situation and Australia is ready to provide support to Tonga if requested.”
