The Pacific country of Tonga experienced a large volcanic eruption followed by a tsunami that flooded parts of the capital, Nuku’alofa, which is lies just 65km north of the volcano.
The eruption of the Hunga Tonga-Hunga Haʻapai volcano sent shockwaves across the South Pacific.
Hunga Tonga–Hunga Haʻapai is a volcanic island in Tonga, located about 30 km south of the submarine volcano of Fonuafoʻou and 65 km north of Tongatapu, the country’s main island.
The volcano is part of the highly active Tonga–Kermadec Islands volcanic arc, a subduction zone extending from New Zealand north-northeast to Fiji.
The island arc is formed at the convergent boundary where the Pacific Plate subducts under the Indo-Australian Plate.
