Videos posted to social media have shown large waves washing ashore in coastal areas.
The eruption Saturday was the latest in a series of spectacular eruptions from the Hunga Tonga Hunga Ha’apai volcano.
Hunga Tonga-Hunga Haʻapai is a volcanic island located about 30 kilometres (19 miles) south-southeast of Fonuafoʻou island in Tonga. The volcano is part of the highly active Tonga-Kermadec Islands volcanic arc, a subduction zone extending from New Zealand north-northeast to Fiji. It lies about 100 kilometres (62 mi) above a very active seismic zone. The island arc is formed at the convergent boundary where the Pacific Plate subducts under the Indo-Australian Plate.
