Waves crash into Tonga homes as Australia and New Zealand issue tsunami warnings

Waves crash into Tonga homes as Australia and New Zealand issue tsunami warnings
Warnings of ‘unusual and unpredictable surges’ have been issued across Pacific region

An undersea volcano has erupted in the Pacific island nation of トンガ, sending large waves which prompted tsunami warnings across the South Pacific.

A video posted to social media showed waves washing ashore on the island nation, swirling around homes and buildings. So far there have been no immediate reports of injuries or the extent of the damage.

ニュージーランド’s emergency management agency issued an advisory on tsunami activity for its north and east coasts stating that some parts of the nation could expect “strong and unusual currents and unpredictable surges at the shore following a large volcanic eruption”.

その間, New Zealand’s military said it was monitoring the situation and remained on standby, ready to assist if asked.

The Hunga Tonga Hunga Ha’apai erupted on Saturday

The eruption of Hunga Tonga Hunga Ha’apai, 約 65 kilometres north of Nuku’alofa, caused a tsunami measuring 1.2 メートル, オーストラリア‘s Bureau of Meteorology said.

Australia’s federal government is also “monitoring the situation” and “ready to provide support to Tonga if requested”.

The Tonga Meteorological Services said a tsunami warning had been put in force for all of Tonga and data from the Pacific Tsunami Warning Center showed waves of 80 センチメートル (2.6 足) had been detected.

Authorities in the nearby island nations of Fiji and Samoa also issued warnings, telling people to avoid the shoreline due to strong currents and dangerous waves. The Japan Meteorological Agency said there may be a slight swelling of the water along the Japanese coasts, but it is not expected to cause any damage.

Tsunami waves measuring two feet in height were also generated in アメリカ領サモア after the volcanic eruption.

声明の中で, the Pacific Tsunami Warning Centre in Honolulu said that “a tsunami was generated by this earthquake. And based on all available data, there is a threat to American Samoa of sea-level fluctuations and strong ocean currents that could be a hazard along beaches, in harbours and in coastal waters.”

Tonga’s Business news site reported that a convoy of police and military troops evacuated the island’s King Tupou VI from his palace near the shore. He was among the many people who headed for higher ground.

Dr Emily Lane from New Zealand’s National Institute of Water and Atmospheric Research said the eruption is “very significant.”

Professor Shane Cronin, School of Environment, University of Auckland, added that the eruption is one of the volcano’s largest since 1100 AD and warned that the people of Tonga should be vigilant of further eruptions of the same size.

“The past large Hunga eruptions were comparable to the scale that we have seen in the 15 1月 2022 event or larger. Based on these past events, tephra (ash) falls of up to 20 cm thick can be expected on Tongatapu and the Ha’apai group of islands. Geological deposits on Hunga Ha’apai of the AD1000 and AD200 eruptions suggest that there were many eruptive phases during each of the major eruption episodes,” Professor Cronin said.

彼が追加した: “This suggests that the current eruption episode could last several weeks or months and that further similar sized eruptions to the 15 1月 2022 event are possible.”

A Twitter user identified as Dr. Faka’iloatonga Taumoefolau posted video showing waves crashing ashore.“Can literally hear the volcano eruption, sounds pretty violent," 彼が書きました, adding in a later post: “Raining ash and tiny pebbles, darkness blanketing the sky.”

The volcano is located about 64 キロメートル (40 マイル) north of the capital, Nuku’alofa. Back in late 2014 そして早い段階で 2015, a series of eruptions in the area created a small new island and disrupted international air travel to the Pacific archipelago for several days.
