As the exceptional amount of water vapour spreads throughout the stratosphere, eyes will turn to the Antarctic ozone hole and just how severe it will be in the spring.’ ![]() However, my gut feeling is that there is more to come from this eruption. ‘Our study nicely shows how the striking display of global waves was driven by the huge amounts of seawater vaporised during the eruption. The eruption produced ripple-like gravity waves that satellite observations show extended across the Pacific basin.Ĭo-author Dr Scott Osprey, Department of Physics, University of Oxford advised that there could be further impacts from the Hunga Tonga eruption: The heat released from the water and hot ash in the plume was the most significant source of gravity waves on Earth for the following 12 hours. 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.Ī multi-institutional international team of researchers combined extensive satellite data with ground-level observations to show that the eruption was unique in observed science in both its magnitude and speed, and in the range of the fast-moving gravity and atmospheric waves it created.įollowing a series of smaller volcanic events beginning in December 2021, Hunga Tonga erupted on 15 January this year, producing a vertical plume that extended more than 50km above the Earth’s surface.
