Atmospheric Effects of Hunga Tonga Eruption Lingered for Years

by Rebecca Owen 22 August 202430 September 2024

A new study builds on previous research of the underwater volcano’s effects on the climate.

A screenshot of a video taken from a deep-sea remotely operated vehicle shows white ash settled on the seafloor near the Hunga eruption in Tongan waters.

The Tonga Eruption Left Deep-Sea Life Buried in Ash

by Andrew Chapman 11 July 202411 July 2024

When Hunga erupted in 2022, ash “decimated” slow-moving species living on the seafloor. More mobile species were able to hoof it out of harm’s way.

Tonga Volcanic Eruption Produced Ionospheric Hole and ‘Bubbles’

by Huixin Liu 10 August 20229 September 2022

The 2022 Tonga volcano eruption altered the global ionosphere, creating a huge ionospheric hole locally near the epicenter and large-amplitude plasma bubbles remotely over the Asia-Oceania area.
