The small island of Mayotte was struck by six-month earthquakes from May to November. Since November 11th, a long monotonic…
On November 11, a low ass began from the eastern coast of Mayotte, northeast of Madagascar and Malawi to the west of the African mainland.
It did not make the news on time because no one knew it.
It’s making the news right now, because it looks like it was all over the planet.
“The waves buzzed across Africa, ringtones in Zambia, Kenya and Ethiopia,” reported Maya Wei-Haas for National Geographic. “They crossed great oceans, humming over Chile, New Zealand, Canada, and even Hawaii almost 1
1,000 miles away.”
What makes the noise so interesting are the two things about what everyone – both researchers and backyard enthusiasts – can agree on. Unnamed:
There were plenty of people wondering and theorizing:
But the chat still continues more than two weeks later.
Despite the fact that the seismic waves rang over the world for 20 minutes, it seems we were lucky to know that it happened. Fortunately, that is, having an earthquake enthusiast in New Zealand passing through the handle @matarikipax who noticed an unusual signal in the United States Geological Survey’s real-time recordings.
The fact is that @matarikipax noted:
And curiosity began to be built immediately.
The University of Plymouth Geology Graduate and Founder of UK Earthquake Bulletin Jamie Gurney said he had “no idea if a similar global signal of this type has ever been observed.”
Volcanologist Dr Robin George Andrews followed up by noting that Mayotte had a “remarkable double-screen volcano” – but the most recent outburst was “2,050 BC”.
Over at NatGeo, Wei Haas went to work and spent the next two weeks interviewing experts and amateurs and trying to get to the bottom of the mystery.
Most people agreed to the waves, from their “surprisingly monotonous, low-frequency ring” to their global spread. “Unique.
” I do not think I’ve seen anything like that, “says Columbia University seismologist Göran Ekström. And he specializes in unusual earthquakes.
There is a lot of fascinating explorative science that shows why Mayo waves are so alien-like.
Bizarrely came the waves after a long series of “traditional” earthquakes ended. They had shaken on the island since May.
Maybe an outbreak will occur. Maybe a whole new island, too.
We may have to surrender it as another tremor, because all we know is something changed.
But it was something big enough to shake the world.
