Reawaking of Tonga volcano
A brief diagram of Hunga Tonga-Hunga Haʻapai Volcano (HTHHV)
After almost 7 years of dormancy, Hunga Tonga-Hunga Haʻapai Volcano (HTHHV) erupted on December 20th, 2021. HTHHV is located in the South Pacific Ocean, 65 km north of Tongatapu, Tonga's main island. The volcano erupted again violently on January 15th, 2022, causing loud booms that were heard across the Pacific Ocean, ejecting 30 km-high ash clouds into the stratosphere, and triggering severe tsunamis; ash from the eruption caused communication networks to collapse.1 Earthquakes continued to occur frequently in the areas around Tonga, even 20 days after the eruption.
