Mega -tsoenamis in Greenland reached 650 feet height, scientists marveled. The mystery is now being resolved | Mint

Scientists decoded an unusual incident that unfolded in September 2023, when seismic stations around the world began to pick up a steady but unusual signal and repeated every 92 seconds. This steady pulse rate lasted nine full days and returned for a short time after a month. It was too faint for people, but to feel strong enough to make his presence feel all over Alaska to Australia – an unusual behavior for a typical earthquake. While scientists were initially confusing, the source was later spotted to the remote Dickson Fjord in East Greenland-a narrow inlet bordering 3,000 feet of high cliffs. A mega -teamami and the mystery behind it showed new satellite images a fresh scar where a portion of the mountain disappeared – indicating that something that was massive hit the water and put the fjord into operation. The answer lies in a colossal natural disaster that hit the area on September 16, 2023. On that day, more than 25 million cubic meters of rock and ice enough to fill 10,000 large Olympic size pools-from the mountain side down in Dickson Fjord. It has moved a mega -teami, with waves reaching heights of 650 feet. These waves rose along the two-mile gait of the Fjord, crashed against cliffs and jumped back and created a Seiche-a long-standing, sloppy movement. Unlike tsunamis, water in seiches goes back and forth in an oscillating movement in a fenced space repeatedly, and for days sends a low frequency seismic energy through the earth’s crust into a steady rhythm. How scientists resolved the puzzle to solve the puzzle, go to the Surface Water and Ocean Topography (SWOT) – a joint mission launched in 2022 by the NASA and the French space agency. With the help of this data, scientists observed the water change changes that were subtly, with slopes of up to two meters and over the fjord. These waves were a match with the oscillation expected of Seiches. Scientists have used machine learning to simulate wave behavior over time to fill the gaps. “It was exciting to work on such a confusing problem with an interdisciplinary and international team scientists,” said Robert Anthony of the American Geological Survey. “In the end, it took an abundance of geophysical observations and numerical modeling of researchers in many countries to put the puzzle together and get a complete image of what happened,” he added.
