Not Another Atlantis Thread

Ok theres a fair few threads about this topic so hopefully this one may be a little different.
I have thought about this alot over the many years since i was first stung by the myth. If we assume that atlantis existed and was in the atlantic would what i am about to write feasable?
I am looking into the possibilty ( If you've read or heard of a theory like mine please u2 me) that a methane pocket below the island collapsed only reason i'm interested in this is because the bermuda triangle is very close to proximity to the bahamian islands. Is this feasable? could this happen?

I've searched alot of websites and in all honestly i've come up with zip. I just find it strange that alot of boats,aircraft have been lost due to this phenomena. If the methane pocket are able to do what they do in water what would they do to a landmass? Would it become like quicksand or would it completely sink below the ocean?

There are several problems with your theory. I'll just run over them briefly:

* methane deposits aren't that large.
* they're found mixed with other hydrocarbons:
www.uwgb.edu...
* there's nothing to erode the pocket and make it grow (see "Karst sinkholes" www.mme.state.va.us... )
* They don't grow to "miles across" size before they collapse from lack of support
* Any civilization advanced to where they were using oil would have spotted the oil rich deposit and would have filled it in as they took the methane out.


...and there isn't any physical or archaeological evidence that Atlantis ever existed.

I watched that Bermuda triangle show with the methane theory to explain for the ships and planes dissappearing.. so I kinda see what you're saying.

and let's just say Byrd's facts aren't true for a moment.

I would think based on what was presented on the show, if such a large methane pocket was to exist under the island it would first explode it to bits before sinking what was remaining, which doesn't quite fit into the Atlantis legend.

Thanks for the response as i said its just a theory and in all honestly didnt know exactly where to look for info about these type of geological processes or there technical terms.

In response to you

1 Admittedly methane deposits arent large however at least 1 methane hydrate desposit the size of a stadium has been found along the B.C. coast of canada and the gulf region near costa Rica is known to have large deposits as well and is estimated to be quite a good spot if/when they have the technology to tap it. Of course methane hydrate in ice like form is not helpful to my theory but it is believed to cause the bermuda triangle effect.
2 Yes from what i've read they are mixed with other thermogenic hydrocarbons however i really dont see the major problem with that.
3 Agree 100% that there isnt anything that could erode or cause a sinkhole to happen in my scenerio. I will look more closely into it though.
4 I agree again however methane hydrate is believed to be twice as abundant as coal/natural gas desposits but i do agree a mile wide deposit is highly unlikely.
5 I dont know where the oil bit came into the equation i've never associated oil with the atlantis myth.

As i said its just a theory that has been floating around in my head for a fair few months of course it would of been better not mentioning atlantis however i just think that the locale made it a interesting theory.

Yeah i see what your saying of course this theory is just evolving and i dont profess to say its more than just a theory. The interesting thing about methane hydrates is that earthquakes and change in water temperature can discharge huge amounts of methane whether this would be enough to sink a landmass the size of atlantis i wouldnt of thought so but then again atlantis' dimensions are put down by plato in a work that most believe isnt based on true events perhaps atlantis was a very small island if it actually existed.
