04-20-2022-0612 - 2022 Hunga Tonga–Hunga Ha'apai eruption and tsunami

On 20 December 2021, an eruption began on Hunga Tonga–Hunga Ha'apai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean. The eruption reached a very large and powerful climax nearly four weeks later, on 15 January 2022. Hunga Tonga–Hunga HaÊ»apai is 65 km (40 mi) north of Tongatapu, the country's main island,[3] and is part of the highly active Tonga–Kermadec Islands volcanic arc, a subduction zone extending from New Zealand north-northeast to Fiji.[4][5]

The eruption caused tsunamis in Tonga, Fiji, American Samoa, Vanuatu, and along the Pacific rim, including damaging tsunamis in New Zealand, Japan, the United States, the Russian Far East, Chile, and Peru. At least four people were killed, some were injured, and some remain possibly missing in Tonga from tsunami waves up to 15 m (49 ft) high. Two people drowned in Peru when a 2 m (6 ft 7 in) wave struck the coast. Preliminary data indicate that the event was probably the largest volcanic eruption in the 21st century, and the largest recorded since the 1991 eruption of Mount Pinatubo.[6] NASA determined that the eruption was "hundreds of times more powerful" than the atomic bomb dropped on Hiroshima.[7]
