New large holes in Siberia.






Looks like a giant sinkhole.
Reminds me of this sinkhole in Columbia

It doesn't appear to be a sinkhole. Notice that the sinkhole has a clean rim around the hole since all material goes down. These have fresh material around the rim indicating it blew up from underneath
 
O.o be it sinkhole or not, how terrifying. Can you imagine, being in your house or on the street, and suddenly...woomf. No ground. Just a big frickin hole. Yikes...
 
No it is not Russia testing new missiles. Can't you all see the obvious here? After the Earth swallowed up some large areas of land, (the sink holes including houses, water and gas mains) Mother nature then suffered some rather bad indigestion and Farted! Who then would disagree that Siberia is the a%#hole of the Earth!!!:eg:
 
We tend to think of the ground as being solid, but there are a lot of hollow spaces under there. Maybe there is just a huge cavern underneath that finally caved in.
 
My first thought was methane ice. WIRED had an article about it maybe ten years ago. It's a single molecule of methane trapped within a buckyball-shaped water molecule (or group of molecules). If you take a handful of it and put it in an empty 1-meter weather balloon, then tie it shut, it will fill up the whole balloon with gas as it melts. That's because the gas occupies more space when it's not trapped in a molecular prison.

This stuff forms naturally at the bottom of the ocean from rotting organic matter. The water is already near freezing. Then as the gas bubbles up it depressurizes, which makes it colder. All this happens beneath the sea floor.

When it erupts, it causes a chain reaction, causing the methane ice around it to erupt. According to some theories, this could result in a bubble of methane so big that when it gets hit by lighting and catches fire, the entire world could be incinerated, resulting in mass extinction. Of course, that's just the more extreme version of the story.

Could there be some link to climate change. I recalled reading that if the global temp rises that you'd have to deal with trapped CO2 and Methane in Sibera?

Aren't these happening in spots that have alot of permafrost?
