Tonga issues tsunami warning after underwater volcano erupts
The peaceful nation of Tonga issued a tsunami warning on Saturday after an underwater volcano erupted
Videos posted on social media showed large waves washing up in coastal areas.
Saturday’s eruption was the latest in a series of spectacular eruptions from the Hunga Tonga Hunga Ha’apai volcano.
Hunga Tonga-Hunga Ha’apai is a volcanic island located approximately 30 kilometers (19 miles) south-southeast of the island of Fonuafo’ou in Tonga. The volcano is part of the highly active volcanic arc of the Tonga-Kermadec Islands, a subduction zone stretching from north-northeast of New Zealand to Fiji. It lies about 100 kilometers (62 mi) above a very active seismic zone. The island arc forms at the convergent boundary where the Pacific plate subducts under the Indo-Australian plate.
