The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.

When the Hunga Tonga-Hunga Ha'apai volcano erupted on Jan. 15, 2022, it sent atmospheric shock waves, sonic booms, and tsunami waves around the world. Now, scientists are finding the volcano's effects also reached space.

A fresh analysis of the possible cooling effect of the sulfur dioxide injected into the atmosphere by the Hunga Tonga-Hunga Ha'apai volcano in January 2022 has concluded that the impact will be much smaller than initially thought--but the researchers responsible add some major caveats to this conclusion.

The atmospheric plume from an underwater volcano eruption in the Pacific nation of Tonga is pictured from the International Space Station as it orbited 269 miles above the Pacific Ocean northwest of Auckland, New Zealand.

On January 13, 2022, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA's Aqua satellite acquired a true-color image of the start of something big--a massive volcanic eruption on from an undersea volcano in Tonga that triggered tsunami waves on January 15which impacted coastal areas from New Zealand to Alaska.

Since the Cumbre Vieja volcano began erupting on 19 September 2021, lava has burned through homes, roads and farmlands causing mass destruction on the west part of the Canary Island of La Palma.

A new study suggests sea discoloration data obtained from satellite images as a novel criterion in predicting if eruption looms for an underwater volcano.

Although there are telltale signs that a volcano is likely to erupt in the near future - an uptick in seismic activity, changes in gas emissions, and sudden ground deformation, for example - accurately predicting such eruptions is notoriously hard.

Instead of looking up to the sky for bright bursts of fiery color, a research team spent Fourth of July 2018 peering down at fiery globs of molten lava from a sky-diving airplane.

The eruption of Kilauea Volcano on the island of Hawaii triggered a number of gas- and lava-oozing fissures in the East Riff Zone of the volcano. The fissures and high levels of sulfur dioxide gas prompted evacuations in the area.

Shiveluch, one of the world's most active volcanoes, is seen poking through above a solid cloud deck, with an ash plume streaming to the west.

One of our planet's few exposed lava lakes is changing, and artificial intelligence is helping NASA understand how.

Volcanoes erupt, they spew ash, their scarred flanks sometimes run with both lava and landslides.

Murray Ford was scanning satellite imagery of a young island in Tonga called Hunga Tonga-Hunga Ha'apai when he noticed something odd--a turquoise plume of water--in the corner of an image.
