Several "new" craters found in Siberia

At least seven newly created mysterious craters have now been officially discovered in Siberia, though satellite imagery suggests there may be as many as 20. The discovery of the first three last year caused a small media storm as no one had any idea how the craters had come about. Since that time, one team of researchers actually went down inside one of the craters to see what might have caused it to come about. That expedition did not reveal any hard facts, but most geologists now suspect that the craters came about due to warming in Siberia, leading to melting permafrost, which led to underground gases filling underground cavities, which led, eventually, to blasts that caused the creation of the craters.

In addition to debating the cause of the creation of the craters, debate has also begun about the term used to describe them—the term crater is usually associated with surface blasts or even more often with collisions between . For that reason, many researchers have begun referring to the craters as funnels.

Thus far, it appears that research regarding the craters is being led by Vasily Bogoyavlensky—a professor affiliated with the Russian Academy of Sciences. In an interview with the Russian press he has indicated that he believes that there are far more craters in and around the Yamal and Taimyr peninsulas and that it appears likely that going forward they may present a . He claims that residents from one nearby town actually witnessed the creation of one of the craters, from a distance—they say they saw a flash and felt the ground shake.

Bogoyavlensky also said that he believes that many of the small lakes in the area likely came about due to the same process as the craters. He added that at one site, a large crater appears to be surrounded by several smaller craters and satellite photos have shown the existence of pingos (mounds that develop on the surface due to ice melting and seeping and then refreezing) in the spots where the craters later formed, suggesting a link. He is calling for more investigation to protect those who may venture into harm's way. Hampering the investigation is the absence of charred rock on the rim of some of the craters, or even a parapet, which should form if a blast came from below. Some have suggested such examples can be explained by noting that evidence may have been left on ice that has since melted.

Pingos (hydrolaccoliths) are not new. Over 1000 can be found in Canada's Northwest Territories.
They are characterized by the presence of water ice and high concentrations of gaseous methane - very strong indications that methane hydrate is being thermally degraded. The hydrate disintegrates at about 12.5° C (55° F) or less, releasing methane and water.
If the methane/air mixture contains over 5% methane, it can be explosive.

terrible picture. Better pics available at http://siberianti...-russia/

They don't look like Pingos.

Are they "just formed" or have they been there a while and we have only just found them ?

Wondering if they use seismic activity to locate them or something?

to get that hole like that would have to be drilled--cause of the dirt off to the side has to be uplfited out then spread on the outside. its like a drill if you drill into a piece wood with a drill an bit you get the same hole and waste on the side just like these hole have. something has to drill this out to do this.

Your comment includes quotes from two commentators. Which of the two are you referring to

If it's @ckirmser I agree.

Gas packet. Likely created from methane/water ice melting. Gas pressure builds as it heats in the chamber, pops the top...

If it is shown to be a result of warming then things could get interesting for sub-Arctic towns built on permafrost. For example Yakutsk, pop. 270,000.
