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

4 years ago to the day, on January 15, 2022, the Hunga Tonga volcano in the South Pacific unleashed one of the most powerful explosions ever captured on visible satellite imagery. The massive underwater eruption generated a trans-Pacific tsunami, while also producing the largest atmospheric explosion recorded by modern instruments—surpassing any volcanic event or nuclear test in recent history, with shockwaves circling the globe multiple times. Like many, I was able to observe the pressure wave

On Jan. 13, 2022, the Himawari-8 satellite captured an explosive eruption of the Hunga Tonga-Hunga Ha'apai volcano, located in the South Pacific Kingdom of Tonga. 🌋 A tidal gauge in Nuku'alofa, the capital of Tonga, measured a one-foot tsunami wave that resulted from the blast.
