THE SIBERIAN BATAGAIKA CRATER IS BELIEVED TO BE THE DOORWAY TO ANCIENT GEOLOGICAL WORLDS from 200,000 years ago - Locals hear strange noises

Locals hear 'booms from the underworld' in giant ravine but now scientists say it holds secrets of the planet's past.
  • Batagaika started to form in 1960s after a chunk of forest was cleared: the land sunk, and has continued to do so, evidently speeded by recent warmer temperatures melting the permafrost. Picture: Alexander Gabyshev
  • Many Yakutian people are said to be scared to approach the Batagaika Crater - also known as the  Batagaika Megaslump: believing in the upper, middle and under worlds, they see this as a doorway to the last of these. 
  • The fearsome noises are probably just the thuds of falling soil at a landmark that is a one kilometre-long  gash up to 100 metres (328 feet) deep in the Siberian taiga. 
  • Batagaika started to form in 1960s after a chunk of forest was cleared: the land sunk, and has continued to do so, evidently speeded by recent warmer temperatures melting the permafrost, so unbinding the layers on the surface and below. Major flooding in 2008 increased the size of the depression which grows at up to 15 metres per year.

THE ALIEN-LOOKING LANDSCAPES OF THE VOLCANIC HYDROTHERMAL FIELDS OF DALLOL, ETHIOPIA

Out of this world! The amazing volcanic hydrothermal fields in Ethiopia that look like the landscape of an alien planet
  • Though named a volcano, Dallol is actually a hydrothermal field located in the northern Danakil Depression
  • Explosion crater was formed by the intrusion of basaltic magma in Miocene salt deposits and hydrothermal activity 
  • Dallol was recently photographed by self-proclaimed 'Lava Hunter' Adrian Rohnfelder, visiting from Germany
  • Dallol is actually a hydrothermal field located in the northern Danakil Depression, despite being known as Dallol Volcano

    MYSTERIOUS UNDERWATER CRATERS FOUND IN THE BARENTS SEA, OFF THE COAST OF NORWAY possibly caused by methane gas explosions - Russian scientist wildly speculates that Bermuda Triangle anomalies could have been caused by methane craters, but there is absolutely no evidence for this

  • Underwater craters found in the Barents Sea off the coast of Norway
  • Caused by build-up of methane natural gas which then explodes
  • Methane explosions on the ocean floor occurred after the last ice age, about 11,700 years ago.
  • The explosions causing the craters to open up could potentially pose risks to vessels travelling on Barents Sea, scientists say.
  • A Russian scientist speculated that the so-called Bermuda Triangle anomalies could be blamed on underwater craters caused by methane explosions, but there is no evidence of this at all.  It just makes for interesting media headlines.

    NEW MASSIVE CRATERS APPEARING IN SIBERIA COULD BE CAUSED BY CLIMATE CHANGE - as underground methane gas may be heating up and igniting - At least one explosion was witnessed at one of the craters

  • Four new craters have been spotted by scientists in the Yamal peninsula, in Siberia
  • May be caused by gas from underground and fear craters becoming more common due to rising temperatures
  • Bright flash of light seen close to one crater which led to theories that buried gas pockets in the soil may be igniting 
  • Another new crater has been found less than six miles from a major gas plant and experts have called for an urgent investigation into the phenomenon 

  • Unexplained: The first of the new craters discovered, named B1 (pictured above), shows signs of an huge eruption of gasUnexplained: The first of the new craters discovered, named B1 (pictured above), shows signs of an huge eruption of gas

    GOING INSIDE ONE OF THE MYSTERIOUS SIBERIAN CRATERS - Scientists to probe for possible origin

    By Anna Liesowska

    • Haunting beauty of massive hole as scientists examine frozen lake formed after giant blowout. 
    • Experts are working on a theory that gas hydrates caused underground explosions in the same way as eruptions under the Atlantic Ocean may have led to the Bermuda Triangle phenomenon.
    • At the base of this hole there is a frozen lake.
    • There are three craters of mysterious origin in the area.
    Exclusive new pictures INSIDE mystery Siberian crater

    A mission this week to the newly-formed crater on the Yamal Peninsula in northern Siberia is expected throw fresh light on how this and other such phenomenon were formed.

    A MYSTERIOUS NEW UNDERWATER CRATER IN UTAH - Collapsing soil may hav triggered small eruption

    Not really huge, but what caused it?
    The central depression is about 17.8cm (7in). The Dalton family were able to push the handle of a pitchfork another 33cm (13in) or so straight down in the soft centre
    The crater was discovered last month by Gary Dalton of Circleville after he saw an unusual hole beneath the water
  • Theories ranged from Martian art to a volcanic eruption– but geologists believe there could be a simpler answer
  • Scientists looking at the crater in Circleville, Utah, claim it was caused by a condition called 'collapsible soils' 
  • The pond has been drained and refilled more than a dozen times in the last two years, causing the soil to give way
  • 'As it collapsed and compacted,' said geologist Bill Lund. 'It forced some air and some water up and created this thing. It looks like a one-off thing'
  •

    Theories so far:

    Some had speculated that the feature was caused by a natural spring, pushing up from under the pond after being supercharged by recent rains. 
     
    Another theory was that a buried pipeline had been punctured during construction of the pond. But experts said there is no pipeline. 
     
    Scientists then proposed that there was a burp of methane gas from decaying organic material under the pond.
     
    Earthquakes sometimes will cause similar features in sand or mud, due to liquefaction of soils. But there have no earthquakes in the Circleville area powerful enough.
     
    The leading theory is a geologic condition called collapsible soils. It suggests that the repeated loading of weight on the soil eventually led some of the soil under the pond to collapse, creating a small eruption.

    MYSTERIOUS CRATERS APPEARING IN RUSSIAN WILDERNESS - THEIR NUMBERS ARE NOW INCREASING

    Crater near Bovanenkovo gas field

  • One of the craters is located in Siberia's Yamal Peninsula in the Taz district and has a diameter of 49ft (15 metres)
  • The other was spotted on the Taymyr Peninsula in Kransoyark region and has a diameter of 13ft (four metres)
  • They follow the discovery of a larger hole found in Yamal earlier this month at around 230ft (70 metres) in diameter
  • Andrei Plekhanov from Scientific Research Center of the Arctic says crater was formed due to rising temperatures
  • One theory is that a chunk of ice that is located underground created a hole in the ground when it melted
  • Another is that the crater was formed by a mixture of water, salt and gas igniting an underground explosion

    MYSTERIOUS HOLE HAS APPEARED IN SIBERIA - The 262ft hole could have been made by a methane explosion or a meteorite crash.

    What on earth is it? This enormous hole has appeared in a remote corner of Russia - and scientists are searching for answers
    UPDATE - More craters found in the region

    The cause of the hole's sudden appearance in Yamal - in the far north of Siberia is not yet known.  One Russian expert says the cause could be global warming releasing gases under the surface, which then explode like a champagne cork.  Experts say that the darkening around the inner rim of the crater indicates 'severe burning' which scorched its edges.

    Dim and distant: Yamal is a corner of Russia far removed from the cities of St Petersburg and Moscow


    Picture on the left - swampy spot in Yamal.  The word Yamal translates as "the end of the world".
