Trembling tundra - the latest weird phenomenon in Siberia's land of craters

This
extraordinary sight - in a video filmed of the tundra on remote Belyy
Island in the Kara Sea off the Yamal Peninsula coastline - was
witnessed by a scientific research expedition. Researchers Alexander
Sokolov and Dorothee Ehrich spotted 15 patches of trembling or
bubbling grass-covered ground.
When
punctured they emitted methane and carbon dioxide, according to
measurements, although so far no details have been given. The reason
is as yet unclear, but one possible explanation of the phenomenon is
abnormal heat that caused permafrost to thaw, releasing gases.
Alexander
Sokolov said that this summer is unusually hot on the Arctic island,
a sign of which is polar bears moving from the frozen sea to the
island.

Scientists
have warned at the potential catastrophic impact of global warming
leading to the release into the atmosphere of harmful gases hitherto
frozen in the ground or under the sea. A possibility is that the
trembling tundra on Bely Island is this process in action.
Further
south, on the Yamal and Taimyr peninsulas, scientists are actively
observing a number of craters that have suddenly formed in the
permafrost.
When
the craters first appeared on the Yamal Peninsula - known to locals
as "the end of the world" - they sparked bizarre theories
as to their formation.
They
ranged from meteorites to stray missiles fired by Vladimir Putin's
military machine and from manmade pranks to the work of visiting
aliens. Most experts now believe they were created by explosions of
methane gas unlocked by warming temperatures in the far north of
Russia.

On
Yamal, the main theory is that the craters were formed by pingos -
dome-shaped mounds over a core of ice - erupting under pressure of
methane gas released by the thawing of permafrost caused by climate
change.
The
Yamal craters, some tiny but others large,
were created by natural gas filling vacant space in ice humps,
eventually triggering eruptions, according to leading authority
Professor Vasily Bogoyavlensky, of Moscow's Oil and Gas Research
Institute.
Recently
there were accounts of a 'big bang' leading to the formation of a
crater on the Taimyr Peninsula.
The
noise could be heard up to 100 kilometres away and one resident. They
saw a 'glow in the sky' after the explosion.

The
crater was first seen by reindeer herders who almost fell into it
soon after the 2013 eruption.
Since
the crater was formed in a 2013 blowout, its size rapidly increased
at least 15 times during the next year and a half.
It
is expected to be even wider now but no recent scientific surveys
have been made to the remote site.
Our
pictures show the so-called Deryabinsky crevice in snow soon after it
was formed, when the hole was some four metres in width, and the
latest known pictures which illustrate how it is now a lake, some 70
metres in diameter.
