Scientists were finally able to identify the elusive earthquake that triggered a tsunami that stretched for thousands of kilometers from the epicenter to the North Atlantic, Pacific and Indian waters in August 2021. As LiveScience explains, scientists initially said the tsunami in question was a 7.5 earthquake near the Sandwich Islands South in the South Atlantic, causing the epicenter to be too deep to cause a tsunami (about 47 km below the sea floor). It was like a rupture of the skeletal plate was causing this. (400 km long) “It must have caused a much bigger earthquake.” A new study published earlier this month in Geophysical Research Letters Journal found that the earthquake was actually a series of five “sub-quakes” and tsunamis. It is suggested that he was there. It resulted in a third earthquake – an 8.2 “invisible” earthquake that occurred 15 km below the surface of the Earth. The earthquake was ah, so it looks like we can avoid detection for a long time. A hybrid of a deep rip and a slow marine earthquake caused by a tsunami. The latter is often difficult to detect, although it can emit “as much structural energy as a major earthquake.”

An earthquake of magnitude 8.2 occurred about 15 km below the Earth’s surface.

Scientists were finally able to identify the elusive earthquake that triggered tsunamis thousands of kilometers from the epicenter to the North Atlantic, Pacific and Indian Oceans in August 2021.

As Live Science explains, scientists initially thought the tsunami in question was caused by a 7.5-magnitude earthquake that was detected near the South Sandwich Islands in the South Atlantic, but the epicenter was very deep. A tsunami (about 47 km below the sea floor) could not be triggered, and the type of structural plate rupture (400 km long) that caused it “should have caused a much larger earthquake”.

A new study published earlier this month in Geophysical Research Letters found that the quake was in fact a series of five “sub-quakes” and that the tsunami was caused by a third “invisible” 8.2 earthquake. It has been suggested. It occurred at a depth of 15 km below the surface of the earth.

“The third event was special because it was massive and quiet,” said Zhi Jia, a seismologist at Caltech, in a statement. “In the data we usually see [for earthquake monitoring]I could hardly see it.

The quake was a combination of a deep rip and a slow-moving marine quake, so it looks like it could have been avoided for a long time. The latter is “often difficult to detect, although it can emit as much structural energy as a severe earthquake. An earthquake of its own magnitude.”

“We think that these complex earthquakes caused the earthquakes of, ‘Oh, they weren’t big, so don’t worry,’ the tsunami hit and did a lot of damage.” Tell. “This study is a great example of how we can understand how these events work and how to detect them more quickly so that we can issue more warnings in the future.”
