There is a Monster Sinkhole/Crater in Siberia that is still growing. Locals think it is cursed and leads to the Underworld. What is cause this? Stealth Aliens? Tectonic Plate shifts? or None of the Above? God bless everyone, T @newTHOR on twitter http://bit.ly/1FL7e16 the article http://bbc.in/2mzm1oS Near the Yana river basin, in a vast area of permafrost, there is a dramatic tadpole-shaped hole in the ground: the Batagaika crater. The crater is also known as a "megaslump" and it is the largest of its kind: almost 0.6 miles (1km) long and 282ft (86m) deep. But these figures will soon change, because it is growing quickly. Locals in the area avoid it, saying it is a "doorway to the underworld". But for scientists, the site is of great interest. Looking at the layers exposed by the slump can give indications of how our world once looked – of past climates. At the same time, the acceleration of the growth gives an immediate insight into the impact of climate change on the increasingly fragile permafrost. There are two types of permafrost. One is from glacier ice, left over from the last Ice Age and now buried underground. The other type, the one present around the Batagaika crater, is ice that has formed in the ground itself. Often, this ice is trapped beneath a layer of sediment and has been frozen for at least two years. The Batagaika crater opens up a vast area of previously buried permafrost, some of which first formed many thousands of years ago. During the last 200,000 years, Earth's climate has alternated repeatedly The trigger that led to the crater started in the 1960s. Rapid deforestation meant that the ground was no longer shaded by trees in the warmer summer months. This incoming sunlight then slowly warmed the ground. This was made worse by the loss of cold "sweat" from trees as they transpire, which would have kept the ground cool. "This combination of less shading and less vapid transpiration led to warming of the ground surface," says Julian Murton of the University of Sussex in the UK. As the ground surface warmed up, it caused the layer of soil right above the permafrost to warm. This caused the permafrost itself to thaw. Once this process started and the ice was exposed to warmer temperatures, melting escalated. For these reasons, scientists are actively monitoring the crater. One study, published in the journal Quaternary Research in February 2017, found that analysing the layers now exposed could reveal 200,000 years of climatic history. During the last 200,000 years, Earth's climate has alternated repeatedly between relatively warm "interglacial" periods and chilly "glacial" periods in which ice sheets expanded. The Batagaika sediment layers provide a "continuous record of geological history, which is fairly unusual," he says. "That should allow us to interpret the climate and environmental history there." The climatic history of a huge part of Northern Siberia is little understood However, for now the dates are not certain. "We are still working on the chronology," says Murton. Next, he needs to gather and analyse more sediments. Ideally, these will be collected using a drill in order to get a "continuous sediment series", which will help give more accurate dates. The permafrost record could then be compared with data from other temperature records, such as ice-cores from ice sheets. "Ultimately, we're trying to see if climate change during the last Ice Age [in Siberia] was characterised by a lot of variability: warming and cooling, warming and cooling as occurred in the North Atlantic region," says Murton. This is important, because the climatic history of a huge part of northern Siberia is little understood. By reconstructing environmental changes that happened in the past, scientists could help forecast similar changes.
