An underwater volcano in the South Pacific erupted violently on Saturday (1/15/2022), causing tsunamis to hit Hawaii, Japan, and Tonga's largest island, Tongatapu -- sending waves flooding into the capital.
The Hunga-Tonga-Hunga-Ha'apai volcano, about 30 kilometers (18.6 miles) southeast of Tonga's Fonuafo'ou island, first erupted on Friday and a second time on Saturday around 5:26 p.m. local time, according to CNN affiliate Radio New Zealand (RNZ). The eruptions sent a plume of ash, gas and steam 20 kilometers (12.4 miles) into the air, according to RNZ. Satellite imagery showed a massive ash cloud and shockwaves spreading from the eruption. Ash was falling from the sky in the Tonga capital, Nuku'alofa, Saturday evening and phone connections were down.
The eruption caused a severe tsunami on Tongatapu, where the capital is located, with waves flowing onto coastal roads and flooding properties on Saturday.
So far, New Zealand authorities have not received any reports of deaths or injuries in Tonga related to the eruption, Prime Minister Jacinda Ardern said at a news conference on Sunday.
