Mega-Tsunamis, which shook the world for 9 days, was revealed in new satellite images

Scientists have finally made the puzzle behind two strange events, the entire planet’s vasyer for nine days in a row. The results they reached closing the book on an effort for a year to track seismic signals to their source.

In September 2023, global earthquake measuring devices discovered something strange. The Earth was suffering from slight tremors every 90 seconds – and the shaking lasted for nine days. After one month, this happened again. Scientists were confused, because natural tectonic processes could not explain abnormal conditions.

About a year after scientific spread, two studies were published in 2024 Independently assumption The shaking has resulted from huge landslides, which led to a decrease in two “Mega-Tsunamis” in the Dickson Strait in East Greenland. These huge permanent waves – or the armies – explode back and forth inside the strait and operate small movements inside the Earth’s crust.

It was an interesting possibility, and both studies provided convincing evidence to support their claims. However, “there were some great uncertainty that made it completely difficult to emphasize that this was actually the root cause,” said Thomas Monohan, a science fellow at Oxford University, told Gizmodo.

Therefore, Monohn and his colleagues set out to confirm whether this hypothesis is correct. In a study published today in the magazine Nature CommunicationsThey unveiled the first direct Satic notes of the Chech and tied them permanently with seismic anomalies.

The researchers used the data taken by a SWOT satellite in SWOT, which is what Firing In December 2022 to Map The water rises across 90 % of the surface of the earth. This type of data collection – known as satellite measurement – works by transferring radar pulses from the satellite to the surface of the Earth, then measuring the time it takes to the signals to bounce from the surface and return to the satellite.

Traditional height devices have failed to capture evidence on Seiches due to the long gaps between the notes, according to Akford statement. As such, they generally struggle to collect data in the strait areas due to the complexity of the terrain. But SWOT is equipped with an advanced height scale tool that uses two air to furnish return signals. This allows the industrial moon to take high -resolution measurements of surface water levels.

“What we can get is basically an incredibly high -resolution snapshot of what the sea rises in these complex areas does,” said Monohan. These shots provided a more accurate picture of how the sea surface height changed in the strait during seismic events for 2023, allowing its search team to calculate the huge wave slopes that were formed.

“We have been able to discover the fact that there is a great homosexuality in the strait when we expect this wave to happen,” said Monohan.

But determining that these Seiches were formed at the same time as strange seismic signals were still not enough to prove that the two events were linked. The researchers needed direct evidence to prove that these huge waves were able to generate global tremors.

To this end, they tied SWOT shots with small movements in the Earth’s crust that was discovered in seismic stations that are located thousands of miles away from the strait. The conjunction of this continuous seismic data with intermittent satellite notes allowed them to rebuild the properties of the wave, even for the periods that SWOT did not notice. The researchers also excluded the possibility that seismicism was caused by the weather or tidal conditions, and they eventually decided that Sech was the sources of tremors.

Monohn said that these waves were formed when a warm ice collapsed on themselves. “This has created the very large ground collapses, which-when they hit the strait-produced a huge huge huge at a distance of 200 meters or 600 feet,” I explained.

“This was the first time that its huge nature in East Greenland has occurred,” Monahan said, adding that this type of events has been documented on the western coast of the lands. He said that seeing this phenomenon is spreading to other parts of the ice cover “related”, because it shows that climate change is accelerating in this region.

“I think what this study truly confirms is that – it seems ridiculous to say – but climate change is a global phenomenon,” said Monohan.

He said: “Some of the largest and fastest changes occur in the Arctic and in remote areas where we may not see them every day. But it is important to understand and measure these changes because they will eventually affect the place where we live.” In fact, the waves that shook the world provide a flagrant reminder of the comprehensive effects of global temperatures.
