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

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

A dramatic video has captured the moment a massive shockwave booms through the air in Tonga after Saturday’s volcanic eruption. 👉 https://bit.ly/tongaboom_1news_160122 It was eventually heard in several countries, including NZ and America. Tsunami waves began hitting the islands of Tonga shortly after this video was filmed. There have been no official reports of any deaths so far. | 1News

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.
