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]
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 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 ...
Multibeam imagery of Ahyi Seamount eruption in 2014. In late April 2014, Ahyi erupted, ending a 13-year dormancy period with an explosive eruption which lasted more than 2 weeks. At the time of the eruption, the remote location of the volcano and the presence of nearby volcanoes made it hard to understand the actual location of the eruption.
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 ...
The existence of a belt of volcanic activity around the Pacific Ocean was known in the early 19th century; for example, in 1825 the pioneering volcanologist G. P. Scrope described the chains of volcanoes around the Pacific Ocean's rim in his book Considerations on Volcanos . [16]
In those, volcanic ash reached from the Pacific ocean to Canada to Mexico. They tend to reoccur about every 600,000 to 800,000 years , according to the U.S. Geological Survey.
