Strange waves rippled around the world, and nobody knows why
National Geographic ^ | Nov 28, 2018 | Maya Wei-Haas

On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world.

The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. The waves buzzed across Africa, ringing sensors in Zambia, Kenya, and Ethiopia. They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away.

These waves didn't just zip by; they rang for more than 20 minutes. And yet, it seems, no human felt them.

Only one person noticed the odd signal on the U.S. Geological Survey's real-time seismogram displays. An earthquake enthusiast who uses the handle @matarikipax saw the curious zigzags and posted images of them to Twitter. That small action kicked off another ripple of sorts, as researchers around the world attempted to suss out the source of the waves. Was it a meteor strike? A submarine volcano eruption? An ancient sea monster rising from the deep?

“I don't think I've seen anything like it,” says Göran Ekström, a seismologist at Columbia University who specializes in unusual earthquakes.

Most earthquakes send out waves with a slew of different frequencies, but Mayotte’s signal was a clean zigzag dominated by one type of wave that took a steady 17 seconds to repeat.

At the risk of breaking out of the Q Anon apartheid homeland, I would point out that this could be written as “a steady Q seconds” on a very significant date, November 11, 2018. ;-)

No, the traces showed almost a perfect sine-wave with no side-bands. Perhaps a Big Angel humming as he worked. ;-)

If a floating island of pumice rock is located in that part of the Indian Ocean, it might verify a volcanic eruption.

I have that... along with about forty or fifty other original releases, special compilations, and boxed sets.

I would not have become a professional chorister if it had not been for Brian Wilson harmonic progressions.

Had this happened off the coast of Japan the Godzilla comments would have been insufferable.

NG articles are very long with loads of diagrams and photos.

An interesting article but, considering the source, (NatGeo), it's surprising that they didn't link this phenomenon to Glowbull Climate Warming Change. Just sayin'.

Lol! Pumice, a volcanic rock, riddled with hollow chambers, does indeed float on water. The only rock that floats. If Hank "Guam may capsize" Johnson's staff or advisors were smart, they would have claimed that he thought the island of Guam was comprised entirely of pumice.

There was a FR thread awhile back (with pics) of a island of pumice in the Pacific Ocean.

#3. Yes, I was thinking close to the same thing but it would be “whale farts”.

Wait a minute. You are right. It was a whale fart, from Al “The Whale” Gore. We were both right.

Now we have to see the results of the fish kills that followed.
