- The tiny island of Mayotte was hit by six-month earthquakes from May to November.
- Then, on November 11, a long monotonous “ring” was measured on Earth.
- Scientists say they "have never seen anything like it."
On November 11, a small rumble began between the northern tip of Madagascar and Malawi in the west of the African mainland, on the northeast coast of tiny Mayotte Island.
At the time, it did not make news, because no one felt it.
It makes the news right now, because it looks like it rattled almost the entire planet.
“Waves buzzed across Africa, ringing sensors in Zambia, Kenya and Ethiopia,” Maya Wei-Haas told National Geographic. "They crossed vast oceans, singing in Chile, New Zealand, Canada, and even Hawaii almost 11,000 miles away."
What makes the noise so interesting are two things about it that everyone can agree on – scientists and backyard enthusiasts. Namely:
- They had never seen it before;
- They have no idea what is going on.
There were many people who wondered and theorized:
But the chat continues for more than two weeks.
Despite the fact that seismic waves swept across the world for 20 minutes, it seems we were lucky that this happened. Lucky enough, that is, to have an earthquake enthusiast in New Zealand, who goes along the handle @matarikipaxwhich noticed an unusual signal in the records of the US Geological Survey in real time.
In fact, @matarikipax noted:
And curiosity began to build immediately.
Plymouth University Geology Graduate and Founder Jamie Gurney's UK Earthquake Bulletin said he "did not know that a similar global signal of this nature had ever been observed."
Volcanologist Dr. Robin George Andrews after which he noticed that Mayotte had a “strange volcano with a double shield”, but the last eruption was “2050 BC. er. "
At Natgeo, Wei Haas went to work, spending the next two weeks talking to experts and amateurs, trying to figure out the secret.
Most agreed that the waves, from their “surprisingly monotonous, low-frequency” ring to their global distribution, were unique.
“I don’t think I’ve seen anything like that,” said a seismologist at Columbia University Geran Ekström. And he specializes in unusual earthquakes.
This is a wonderful piece of fascinating research science that explains why Mayotte waves are so alien.
Surprisingly, the waves appeared after The series of “traditional” earthquakes continued. Since May, they shook the island.
Maybe an eruption is coming. Perhaps even a completely new island.
We may have to pass it on as just another tremor, because everything that we know something shifted.
But it was something big enough to shake the world.
