Title: Mysterious Siberian Crater Found
Post by: noviapriani on July 17, 2014, 03:38:07 PM
Since i didn't understand what 247crypto posted, i researched on google and here what i found :
A mysterious crater almost the size of a football field discovered in a remote part of Siberia's Yamal peninsula known as the end of the world may have profound implications about the stability of Arctic methane  and catastrophic climate change.

    The striking puncture in the earth is believed to be up to 80 metres wide but its depth is not estimated yet. A scientific team has been sent to investigate the hole and is due to arrive at the scene on Wednesday.

    The cause of its sudden appearance in Yamal - its name means the 'end of the world' in the far north of Siberia - is not yet known, though one scientific claim is that global warming may be to blame.

Russian experts have ruled out speculation that meteorite impact might have caused the crater. The crater was certainly not caused by a meteorite because it has no central crater but instead has a deep hole. Meteorite impacts have far too much energy to leave an open hole. (Note: I studied meteoritics for my first year of graduate school.)  Likewise any other extraterrestrial source would have far too much energy to leave an open hole. The impact site would be filled with ejecta.

It doesn't appear to be a sink hole because the hole is surrounded by a rim of ejected material. Genarally, sink holes don't have elevated rims because they are produced by collapse of surface material into a preexisting covered hole. The ejecta appears to have been produced by an explosion. This crater formed in one of Siberia's largest natural gas producing regions. Permafrost in this area is melting in response to the rapid warming of the Arctic. The most likely cause of this crater is a methane explosion.
    Anna Kurchatova from Sub-Arctic Scientific Research Centre thinks the crater was formed by a water, salt and gas mixture igniting an underground explosion, the result of global warming. She postulates that gas accumulated in ice mixed with sand beneath the surface, and that this was mixed with salt - some 10,000 years ago this area was a sea.

If Dr Kurchatova's explanation is correct, the consequences are profound. It means that There are vertical structures where salt accumulated as methane ices formed in permafrost. Layers of permafrost may have salty vertical zones of weakness in them that will allow sudden release of methane trapped below the permafrost layer as the climate warms. Vast quantities of methane trapped in river deltas in the Arctic ocean on the Siberian shelf may be unstable. This crater appears to be evidence that the methane is not protected by a very slowly melting solid layer of permafrost. Methane bubbles recently observed in the Laptev Sea, reported on by the National Science Foundation, could be the beginning of the release of an enormous amount of subsea methane.
Methane is escaping from shallow subsea sediments on the Siberian platform. This National Science Foundation diagram shows Siberian platform methane bubbles rising to the surface and entering the atmosphere.

The concerns of a methane catastrophe expressed by scientists who have discovered large amounts methane escaping from the Laptev Sea may reinforced by this land based observation of methane instability in Siberian sediments of marine origin. Extraordinarily high methane levels were observed over the Laptev sea in fall 2013.
Very high methane levels were observed over a 30 day period over the Laptev sea, November, 2013.

Harold Hansel who generated this graphic of methane levels over the Laptev sea expressed alarm:

    "I am fighting for the lives of my children, grandchildren, and great grandchildren who's lifespan will extend 30 to 40 years from now. I am also fighting for all children of the world, animals, whales, dolphins, flowers and all living things. They are all in peril and we are the ones that may have a chance of doing something about it now. The threat of what is coming must sink in."

I have been waiting for independent evidence of methane instability in Siberian sediments to validate the concerns that the Siberian platform could produce a rapid release of methane, a far more potent greenhouse gas than CO2, that could destabilize the climate. I am afraid that it has just been found.

Hey thanks for researching this. I saw the post and from the video I could tell it was not a meteor strike, but I could not tell if it was a CGI hoax.
If that thing is real... then WTF? I had no idea that methane in the permafrost could behave that way or form a structure like that. I can't wait to find out more! How deep is it? Are there others? It looked to me like the "blue hole" I used to dive in Belize. That feature is interpreted as a Karst feature, but could it be related?

In any case, I hope this is not a sign of the permafrost going. If that happens the volume of green house gas entering the atmosphere would be staggering. There would be little we could do to keep the planet from becoming an oven. It is considered the worst case scenario in global climate change.

10 000 years ago humans were conducting nuclear tests on dinosaurs. Godzilla was born. Godzilla was so mad he became hot like the sun and the sea were he was bathing evaporated. The methane we have now is highly concentrated Godzilla fart.

Yamal is the main natural gas producing region of Russia. So there could be methane deposits within this hole. There is a real danger of explosions occurring in the vicinity.

Looks fake.  Nature doesn't have straight lines.   :-\

Well... I got the pic from the Associate Press. I thought that they were a reliable source.

In the video the Yamal crater/hole has what appear to be streams of dry material falling into it. Its depth has not yet been determined. Update: latest measurements estimate the depth of the hole to be 50-70 meters. source: http://siberiantimes.com/science/casestudy/news/first-pictures-from-inside-the-crater-at-the-end-of-the-world/

There are huge deposits off the east coast.   They have from time to time created massive waves and serious destruction that travels across oceans.  Its only a matter of time.  I have no idea where flood legends come from.

Looks damned impressive :) Interested to see what develops with this, those smooths sides are freaky, little doubt its something natural but can't help thinking of those bunker buster weapons (anything man made would surely show up in soil samples though).
The climate has been changing since dinosaurs walked the earth, it's probably the reason they no longer walk the earth.  And MAN had nothing to do with that and has nothing do do with any change that is happening now.  There's not a damn thing we can do about it,but the liberals are milking this cow for all it's worth to advance their agenda of global social justice. They won't make any difference either.  This planet has it's own rhythms and will follow it's own script.  Anyone who thinks they have the slightest ability to make one degree of difference is delusional.

I know a lot of folks have their various biases in the argument of global climate change, but there are several aspects that are far more frightening that just warming.   Warming is fine by me.  I like warm.  Warming too fast means the buffers from rivers cant keep up with changing pH.  This is ocean acidification.  This  has been happening in recent decades with increased pace.  Some shell-forming animals are already reportedly having problems.  Google Ocean acidification if interested

The other is the unknown factors....like methane hydrates in the deep oceans.  What will a very slight change in deep ocean temperature do to possibly release vast deposits? Or a rapid change?   It is not so much that change has happened, rather how fast it happens and the differences that makes.

Methane is even more dangerous than CO2. The entire polar ice-caps can melt, if vast amounts of methane is released into the atmosphere.
