Strange seismic waves originating off French Madagascar

a reply to: grey580

I almost made a Godzilla joke in the OP!

I love when we don't have a textbook answer. We're not always quite as smart as we think we are.


The bloop is a fun topic, too.

The Bloop - i was fascinated by this but apparently it is just ice shelves breaking off - according to this, anyway:

The Bloop mystery has been solved; sort of

Disappointing - I wanted it to be Cthulu although maybe not, come to think of it.

But, I have heard about this thing that sonar operators are banned from talking about and would love to know what that's all about.

I was treating a sonar operator that came in for chest pain (undisclosed location). One of the medications I use is Morphine. I was just making small talk with him while I observed his vital signs and asked him what he did. He said that he was a sonar operator in a sub. I asked him if he ever saw anything weird down there (not expecting an answer back). He then told me that he had tracked an object that was three times the size of an aircraft carrier, that was below crush depth, traveling over 500 knots. The conversation continued, but I currently can't recall the details.

Yes, they see some strange stuff.

Very interesting - thanks. I'd love to know more about this stuff.

This hypothesis proposes that intense low frequency hydroacoustic compressions and rarefactions (seaquakes) generated bycertain undersea earthquakes can induce barotraumatic injuries in the sinuses, air sacs, and middle-ear air cavities of submerged whales and dolphins. Healthy cranial air spaces are essential for both diving and the proper functioning of the odontocete biosonar system. Thus, a pod of whales or dolphins injured by a seaquake will find it impossible to dive and feed themselves and to echonavigate the open ocean. Such disoriented pods will swim down stream in the path of least drag/resistances. Beaches are built by the same current controlling the swim path of the lost whales, which explains why lost whales and dolphins usually strand in sandy areas.

A couple of years ago, TrueAmerican authored a thread titled, "Better hope there is not a big earthquake or nuclear blast somewhere...," in which I asked if he thought that the military might have its own seismic network. His answer was, "They have first tier access to the data, no doubt, from nearly all of them."

This was in the context of having certain signatures filtered out by the military before any scientist was able to access the data due to the possibility that certain equipment might be detected or capabilities determined from signals that could be registered by seismometers.



From Live Science:

And yet, a Nov. 12 report from the French government found that Mayotte had slid 2.4 inches (6 centimeters) to the east and 1.2 inches (3 cm) to the south.

Here is the helioplot as well as the spectrogram reading of the event.


For those who may not be familiar with reading spectrograms of earthquakes, it must be noted that this event contained very low (from the 1hz range on up) frequency energy, this is characteristic of tectonic or volcanic signatures. In order to have such low frequency response of the indicated intensity, there must be a large area of movement, otherwise the wavelength could not be generated.

Also of interest is the distance which this signature propagated. Generally, only events of around M6 or greater will have enough energy to propagate that far. This is why many deep earthquakes don't have many recorded aftershocks; the smaller earthquakes don't propagate to the surface for them to be registered by the seismometers.

Something to keep an eye on for certain.

So maybe we are on to the "slow-quake" hypothesis. Instead of a sudden snap or jolt, you get a low-acceleration slide occurring over several minutes?

Could solar activity have anything to do with this? I understand it can have a considerable impact on geologic activity here in Earth, but would be lying if I said I understood it fully.

I ask because if my shoddy memory serves me correct, aren’t we about to transition into a solar minimum? Our magnetic field is weaker because of it as I recall. Maybe there’s some solar activity going on that could affect our geologic process??

Just a thought.

An investigative researcher authored a piece a few months back on a few different topics which included some strange things on an island group very close to this one. Including a weird structure.

Interesting possibility.

Interesting players involved as well.

Anyone farmilliar with what this odd structure might be?

The mysterious structure looks like a cattle pond. Doesn't make me want to read whatever else in the article.

a reply to: RadioRobert

Is that what that is? It seems reflective and there are other structures that seems odd pointed out in article. They aren't the focus of the article though, just an aside.

The article's focus is about renewable energy initiatives in many different places that happen to include this island group.

It delves into a lot of interesting info , though not directly related to your op topic.

Eta. I can't find any cattle ponds that look like that, the inclines on the side seem way too much for cattle also it does seem reflective.

Could be wrong!

OK, I'm intrigued. A blue whale is the largest known animal, and it gets to be around 100 feet (30 meters) long. A Nimitz-class carrier (which I assume he was thinking of) is over 1000 feet long. An object 3 times longer than that far exceeds any known creature that has ever lived.

Yeah, the, "mysterious disk," is actually some sort of depression. It looks to be on the rim of an extinct volcano.

Looking at the area tilted at an angle where the "disk" is, one can see the remains of the crater upon which the item in question is located:



As much hinky stuff there is surrounding the Clintons, I don't think this has one iota of involvement with anything they are associated with.

a reply to: jadedANDcynical

So maybe what appears to be reflective is rock.

Eh I knew it was a shot in the dark, earthquakes, Clintons. You never know.

It's true the depression doesn't look very man made.

This is the kind fo stuff that I actually hope to find when I come to ATS.

Thanks.

I'm here for the Trump posts mostly nowadays.

11/11 maybe its something else we don't understand, I've seen these numbers in sequence hundreds of times in the last year

Could it be a large deep underground cavern collapsing due to the recent swarm of tremors and EQs? Or would that register like a normal EQ?

it does but if a Clinton is involved there is usually something stinking.

If you read the whole thing it has a lot of mystery. it seems though this island is on the move possible magma uplift.

“They're too nice; they're too perfect to be nature,” she jokes, although she quickly adds that an industrial source is impossible, since no wind farms or drilling are taking place in the deep waters off Mayotte's shores.

Here it is in Google Earth from 2005 (oldest imagery available):



Note that the water level is much higher.

It's not something that's a new phenomenon.
