The Hunga Tonga Hunga Hapai volcano shook the world during the eruption in January this year. It created tsunamis across the Pacific Ocean and other oceans, and even lifted clouds over the United Kingdom for more than 16,000 kilometers. But surprisingly, the underwater volcano remains intact.
The data came after a month-long study by the National Institute for Water and Atmospheric (NIWA) in New Zealand. The NIWA posted the results of their study on Twitter, saying it “rejected scientists’ expectations.”
The study was conducted by a ship that reached near the volcano to create post-eruption maps of Hunga-Tonga Hunga-Hapai and the surrounding seabed.
NIWA scientists say their ship RV Tangaroa has recorded displacement of up to seven cubic kilometers – the equivalent of 3 million Olympic-sized swimming pools. But, despite the ash, the volcano has stood tall.
The 2/6 eruption displaces at least 7 cubic kilometers of material, and changes have been observed in the vicinity of 8,000 sq km of the 22,000 sq km mapped by RV Tangaroa, with 50 m thick ash and debris under the sea floor.

The NIWA said in a tweet that “scientists have still found ash in the water column, suggesting that the volcano may still erupt, with oxygen-related depletion, meaning the potential effects of food production and carbon sequestration,” the NIWA said in a tweet.
Campaign leader Kevin McKay said he was surprised by the results of the study.
“In light of the violence that erupted on January 15, I expected the building to either collapse or collapse, and that is not the case,” he said. BBC.
Mr McKay said the seabed had shown some dramatic effects of the eruption, such as fine sandy mud and deep ash waves 50 km from the volcano, including a yard of valleys and huge mounds of silt.
The volcanic eruption, the strongest in a century, was heard as far as Alaska and tore apart an 80-kilometer stretch of telecommunications cable at the bottom of the Tonga Sea. The small island’s telecommunications system was severely limited and it took experts about a month to recover.
