NASA has followed the Pacific Islands evolution for years. Then Hunga Tonga-Hunga Ha’apai erupted. 🌋 “It gave us a window into a rapid-paced life history of an island that we can compare to hundreds of other islands in the oceans over time,” said Jim Garvin, Chief Scientist at NASA Goddard. Through the eyes of NASA - National Aeronautics and Space Administration and ESA - European Space Agency satellites, scientists are able to study the life cycle of volcanic islands – from formation to erupti

High-resolution Himawari satellite imagery of the Hunga Tonga-Hunga Haʻapai volcanic eruption in Tonga 🌋 Our climate stations recorded a brief spike in air pressure as the atmospheric shock wave pulsed across New Zealand. From Civil Defence: "We have issued a NATIONAL ADVISORY: TSUNAMI ACTIVITY following the Tongan eruption. We expect New Zealand coastal areas on the north and east coast of the North Island and the Chatham Islands to experience strong and unusual currents and unpredictable surg

The Hunga Tonga–Hunga Haʻapai is a volcanic island in Tonga that was effectively erased by the massive underwater eruption in January 2022. Formation and destruction: The island initially formed in 2014–2015 from volcanic activity. However, the catastrophic eruption on January 15, 2022, obliterated much of the island — satellite radar data revealed that most of the land had vanished, leaving only remnants of the original structures. #geology #geologyfeatures #geologist #geologywonders | Geology

The Largest Eruption on Earth Ever Caught on Camera The Hunga Tonga-Hunga Ha'apai Eruption: A 100-Hiroshima Bomb Blast The 2022 eruption of Hunga Tonga-Hunga Ha'apai volcano is often compared to a simultaneous detonation of 100 Hiroshima-sized nuclear bombs. This massive explosion released an enormous amount of energy, causing widespread destruction and affecting the environment globally. | Science Sphere

NEW: Researchers discover the Hunga Tonga-Hunga Ha’apai volcano triggered atmospheric gravity waves that reached the edge of space. The waves reverberated around the planet at least six times and reached close to their theoretical maximum speeds – at 320m per second or 720mph. The study also confirmed 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.
