Hunga Tonga–Hunga Haʻapai is 65 kilometres (40 mi) north of Tongatapu, the country's main island, [9] and is part of the highly active Tonga–Kermadec Islands volcanic arc, a subduction zone extending from New Zealand to Fiji. [10] [11] On the Volcanic Explosivity Index scale, the eruption was rated at least a VEI-5.
Now, “vast areas of the reefs in the immediate impact area at Hunga Tonga are probably buried and smothered by large deposits of volcanic ash,” said Tom Schils, a marine biologist at the ...
Hunga Tonga–Hunga Haʻapai is a submarine volcano in the Kermadec-Tonga Ridge in South Pacific, a ridge formed by the convergent boundary where the Pacific Plate is subducted by the Indo-Australian Plate, forming a long volcanic and island chain. Hunga Tonga–Hunga Haʻapai volcano lies almost completely underwater, with the exception of two ...
Atmospheric scientists report that the 2022 volcano eruption in Tonga, Pacific Ocean – the largest recorded volcanic eruption since 1991 which reportedly cooled global climate by ~0.6 °C during 15 months [32] – did not have a cooling effect (volcanic winter) of significance to global climate change (i.e. a cooling of ~0.004 °C during the ...
For the South Pacific island nation of Tonga, the tsunami unleashed by Saturday's volcanic eruption laid bare some of the ways that climate change is threatening the islands' very existence. By ...
The eruption of Hunga-Tonga-Hunga-Ha'apai volcano, which sits on the seismically active Pacific Ring of Fire, sent tsunami waves across the Pacific Ocean and was heard some 2,300 kms (1,430 miles ...
Tofua caldera. Tofua is a volcanic island in Tonga.Located in the Haʻapai island group, it is a steep-sided composite cone with a summit caldera.It is part of the highly active Kermadec-Tonga subduction zone and its associated volcanic arc, which extends from New Zealand north-northeast to Fiji, and is formed by the subduction of the Pacific Plate under the Indo-Australian Plate.

It’s possible for volcanoes to have a short-term impact on the climate – including global temperature cooling – due to the gases they inject high into the upper atmosphere.
