Chemical reactions triggered by Hunga Tonga eruption led to severe stratospheric ozone depletion

Chemical reactions triggered by Hunga Tonga eruption led to severe stratospheric ozone depletion

On January 15, 2022, the Hunga Tonga–Hunga Ha’apai underwater volcanic eruption led to a sudden and significant loss of stratospheric ozone. This event occurred over the tropical southwestern Pacific and Indian Ocean region. Researchers found that the eruption injected an unprecedented amount of water vapor into the stratosphere, causing chemical reactions that resulted in rapid ozone depletion.

Corrosive ash from massive 2022 Hunga Tonga-Hunga Ha’apai eruption causes power crisis in Tonga

Corrosive ash from massive 2022 Hunga Tonga-Hunga Ha’apai eruption causes power crisis in Tonga

Corrosive ash fallout from the massive eruption of Hunga Tonga-Hunga Ha’apai volcano last year has triggered a series of power outages on Tonga’s main island, Tongatapu, beginning September 2022. Tonga Power, the island’s electricity provider, has termed the situation a “crisis” due to the unprecedented damage to the High Voltage Aerial Bundled Cabling across the island.

Hunga Tonga–Hunga Haʻapai volcano eruption triggered unprecedented ionospheric disturbances

Hunga Tonga–Hunga Haʻapai volcano eruption triggered unprecedented ionospheric disturbances

An international team of scientists revealed that the massive eruption of the underwater Hunga Tonga–Hunga Haʻapai volcano in Tonga on January 15, 2022, disrupted satellite signals across the globe. The team used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by the volcanic eruption could produce an equatorial plasma bubble in the ionosphere, severely affecting satellite-based communications.

The greatest concentration of lightning ever recorded

The greatest concentration of lightning ever recorded

The Hunga Tonga-Hunga Ha’apai volcano eruption on January 15, 2022, has set a new record for the greatest concentration of lightning ever detected. According to data from Vaisala’s Global Lightning Dataset GLD360, nearly 400 000 lightning events were detected within just six hours of the eruption, making it a truly exceptional phenomenon.

The fullest investigation of the massive Hunga Tonga-Hunga Ha’apai eruption to date

The fullest investigation of the massive Hunga Tonga-Hunga Ha’apai eruption to date

In January 2022, Hunga-Tonga Hunga-Ha’apai (HT-HH) emitted the biggest atmospheric explosion recorded on Earth in more than 100 years. Several months after the eruption, a New Zealand-led team has completed the fullest investigation to date into the eruption of this underwater Tongan volcano.

Volcanic twilights over New Zealand

Volcanic twilights over New Zealand

Very high concentrations of aerosols originating from the plume of volcanic gas and ash produced by the massive eruption at Hunga Tonga-Hunga Ha’apai volcano on January 15, 2022, are now causing stunning, fiery colors in the sky over New Zealand.

Hunga Tonga-Hunga Ha’apai eruption caused a major space weather event

Hunga Tonga-Hunga Ha’apai eruption caused a major space weather event

When the Hunga Tonga-Hunga Ha‘apai volcano in Tonga erupted on January 15, 2022, it sent atmospheric shock waves, sonic booms, and tsunami waves around the world. Now, new research published in Geophysical Research Letters shows the effects of the eruption also reached space, causing a major space weather event.
