In September 2023, an extraordinary earthquake signal used to travel around the world for nine consecutive days every 90 seconds and was repeated a month later. Scientists were initially unable to identify the source. About a year later, two scientific studies suggested that the cause of the earthquake was two mega tsunami, which was mobilized by two major land sliding in remote East Greenland Fijord, which was caused by an unknown glacier heat. It is believed that these events have opened the mega -census, which was then trapped as Seaches. Until now, observations of these seches were not available to confirm this theory. In a new study, scientists have first direct observations using novel analysis techniques to translate satellite ultimate data.
Using SWOT
According to the new research, the progress has come from the surface water and the sea tipography (SWOT) satellite. Traditional satellite ultimators failed to detect waves due to their splendor and linear data coverage. On the contrary, SWOT’s band radar interface (carin) offers extraordinary local resolution and measures surface water heights with a 50km wide swash of 2.5 meters.
Researchers analyzed SWOT data during the events and after the FJRD height maps. These maps revealed a separate cross -channel slopes that moved in the opposite direction, which provided definite evidence of the Sichs. Although a Denmark military ship did not see any obstacles in Fijord during the event, the widespread neglect of SWOT did not capture their eyes and old equipment.
The climate -driven extremity
Researchers confirmed that Sichies had presented a long earthquake for nine days, connecting these observations to the earthquake indicators and rejecting other reasons such as air or maize.
“Climate change is giving birth to new, unseen,” said Thomas Monhan, a leading author of the unseen. “This study shows how satellite can help us study Earth.” “SWOT is a game changer, co -author Professor Thomas Adekak added. We have to connect machine learning and marine physics to fully use its data.”
