In December 2021, an eruption began on Hunga Tonga–Hunga Haʻapai, a submarine volcano in the Tongan archipelago in the southern Pacific Ocean. [7] The eruption reached a very large and powerful climax nearly four weeks later, on 15 January 2022. [8]
The volcanic island of Anak Krakatau in Indonesia saw an eruption on 22 December 2018 which caused a deadly tsunami, with waves surging up to five meters in height. The tsunami killed at least 437 ...
Its most recent eruption in January 2022 generated a tsunami that reached as far as the coasts of Japan and of the Americas, and a volcanic plume that reached 58 km (36 miles) into the mesosphere. As of February 2024 the eruption is the largest volcanic eruption in the 21st century. Hunga Tonga–Hunga Haʻapai likely had a previous major ...
The tsunami threat around the Pacific from a huge undersea volcanic eruption began to recede Sunday, while the extent of damage to Tonga remained unclear. Satellite images showed the spectacular ...

An explosive volcanic eruption occurred near the Kingdom of Tonga, a nation of 170 islands in the southwestern Pacific Ocean, causing tsunami waves to impact the region and ash to fill the sky. A ...
Using geochemistry, radioactive dating and computer modeling to map particles’ trajectories, the scientists linked the 1831 eruption to an island volcano in the northwest Pacific Ocean, they ...
After a volcanic eruption, evaporation over ocean will lower, because it is largely determined by the ocean surface temperature change. The quick response of evaporation to the surface cooling and the delayed response of river runoff to the associated lower precipitation lead to an increased sea level.
