- The Mayotte small island was hit by six months of earthquakes from May to November.
- Then, on November 11th, a long monotone "circle" was measured across the Earth.
- Scientists say they have never "seen anything like him".
On 11 November, the lowland coast of the northeast of the island of Mayotte began to rumble low, which has restricted the northern tip of Madagascar and Malawi to the west on the mainland of Africa.
He did not make the news at the time because nobody felt that.
He does the news at the moment, however, because he looks like it is only wandering about the whole planet.
"The waves were charming across Africa, calling sensors in Zambia, Kenya and Ethiopia," Maya Wei-Haas reported for National Geographic. "They crossed extensive oceans, wandering across Chile, New Zealand, Canada, and even Hawaii almost 11,000 miles away."
What makes the noise so interesting is the two things that everyone – scientists and enthusiastic about the backyard alike – can agree on it. Truly:
- They have never seen that recorded in front, and;
- They do not know what's happening.
Lots of people were amazed and theories were:
But the conversation is still more than two weeks later.
Despite the fact that the seismic waves are fogging around the world for 20 minutes, it seems we are fortunate to know it has happened. Luckily enough, that is, he has an enthusiastic New Zealand earthquake that goes through the hand @matarikipax, and notice an unusual sign in the real time recordings of the US Geological Survey.
Indeed, @matarikipax noted:
And construction curiosity began immediately.
University of Plymouth Geology Graduator and founder UK Earthquake Bulletin Jamie Gurney said she did not have "no idea if a similar global sign of this nature has ever been observed".
Volcanoleg Dr. Robin George Andrews followed by saying that Mayotte has "a strange double-shielded voltage" – but this is the last ever "2,050 BCE" name.
During NatGeo, Wei Haas went to work, spending the next weeks interviewing experts and amateurs, trying to reach the bottom of the mystery.
Most agreed that the waves, from their "surprising monoton", "low frequency" to a global spread ", were unique.
"I do not think I've seen something like it," said Göran Ekström, a University of Columbia seismologist. And he specializes in unusual earthquakes.
It's a great piece of interesting investigative science that comes into why why Mayotte waves are so strange.
Unfortunately, the waves came after A long series of "traditional" earthquakes ended. They had been shaking the island since May.
An explosion may come. Perhaps a whole-island island, even.
We may have to pass it as just another wandering, because of what we know is something move.
But it was something big enough to shake the world.
