Seismic sensors first brought the event that originates from an island between Madagascar and Africa. Then the alarm bells began calling as far away as Chile, New Zealand and Canada.
Hawaii, almost exactly on the other side of the planet, also took up the “event”.
Nobody knows what it was. 19659002] meteorit? Submarine Volcano? Nuclear Test?
“I do not think I’ve seen anything like that,” National Geographic reports Columbia University seismologist Göran Ekström as saying. “It does not mean that in the end, the cause of them is exotic.”
In the middle of the mystery lies the small island of Mayotte, located approximately halfway between Africa and Madagascar. It has been exposed to an earthquake heat since May. Most have been smaller, but the largest ̵
1; May 8 – was the largest recorded island history, peaked at an order of 5.8.
But the earthquake heat had decreased before the mysterious ring was discovered earlier this month.
Ekström, specializing in unusual earthquakes, highlights the event on November 11 was strange. It was as if the planet rang like a bell and maintained a low-frequency monoton when it spread.
Earthquakes, by nature, usually register as short-cut “cracks”.
As tensions in the earth’s crust
The first signal is called a primary wave: high frequency compression waves radiating in bunks.
Then comes a secondary wave: these high-frequency waves tend to “fold” more.
Only then will the surface waves: These slow deep asses tend to linger and can circle the earth several times.
The November 11 event is remarkable because no Primary or Secondary waves were detected.
Everything that was recorded was the deep, resonated surface wave. And it did not shine like the earthquake’s surface wave tends to. Instead, it kept a much cleaner – almost musical – frequency.
National Geographic reports the French Geological Survey suspects that a new volcano can develop beyond Mayotte. While the island was created by volcanic activity, it has been resting for more than 4000 years.
The French believe that the strange ring could have been generated by a magic movement about 30 miles off the coast and under deep water. This is supported by GPS sensors that detect Mayotte have moved about 2 inches to the southeast in less than five months.
But it’s a badly mapped region. Exactly what under the sea can only be guessed.
Ekström believes that the unusually pure signal could have been caused by magma wasted inside a chamber or forced through a gap in the underground mountains.
But he is not sure.
