Located within the islands of Southern Antarctica in Shetland, it is considered that the remote island of Deception Island is the largest active volcano in Antarctica Point.
The whole island was cleared when a large volcanic drainage was given to him, which gave his horse shape as a signature – an explosive event so powerful that he would drop his volcano on himself and He finished five miles in the middle of the island.
Once the caldera was filled with ocean water, the Isle of Deception became a stunning landscape that we know today – "a rock ring on a shaped shape around a bowl with water , "sea Forbes tells about it. Although many volcano experts know some time to start the island's violent start, this cascolic horror line was largely a puzzle – that is so far.
Previous estimates of volcanic breakdown at about 10,000 years ago, as shown in this report by National GeographicIn the West However, the approximate time window of this Late Pleistocene sword event was about 126,000 years ago recently in the history of our planet – just a few thousand years ago.
The final mystery is subdivided by a team of dramatists, reports OnwardsNext Post In the publication published last week Scientific Reports, the team argues that a massive volcano crash has shaped the Island of Deception 3,980 years ago – it will take a year or give it.

According to media media, the team first measured the climate changes recorded in this Antarctica over the last 11,700 years – or from the end of the last Ice Age. To find out how the area's weather changed over time, the team traveled by Dermot Antoniades from Laval University in Quebec, Canada to nearby Livingston Island and explored the sediment centers from a number of lochs in Letterkit.
The journey, which was made between 2012 and 2014, made them unexpectedly falling – a thick layer of volcanic debris found in four lakeside 25 miles away from Eilean Deception. Made up of volcanic springs, the rubble was found under two rows of younger sediment – secretly arranged after the same pattern in the four settings.
As described by the composer of Santiago Giralt, the volcanic window was excavated from a smaller degree of 40 inches; an inhabited place, "drawn from loch shores" and dropped below after a "big earthquake" – covered by a new series of "common loch sediments" that collects in the this ecosystem.

Geochemical and biological studies have subsequently revealed that the volcanic debris had started on ground and was created rapidly in the same brutal breach. In addition, scientists were able to make sure that the skeletons of a similar belief that created a genuine believer were genuinely created when the surprise was surprised Eilean Deception on her map – to literacy.
"These results suggested that there was a huge earthquake that has an impact on the whole area, and we put on the way we did not look at a common earthquake – but one that was created by to boil the island of Deception Island volcano. From here, we put the thread away, "said Giralt, a researcher at the Institute of Earth Sciences Jaume Almera (ICTJA-CSIC) in Barcelona, in Spain.

Once the team did not Analyzing the sediment worms found from the four Byers Peninsula, scientists can build a date for the large volcano burst – the largest one; in Antarctica in the last 12,000 years.
"This incredible event of intestinal casualties was thrown between 30 and 60 cubic kilometers rapidly [roughly seven to 14 cubic miles], comparatively in the volume of Tambora's volcano waulking in 1815 – an event set for global warming that has resulted in poor harvesting in Europe, in what is known as summer and summer, & # 39; Explained by the author of Adelina Geyer, also from ICTJA-CSIC.
The recent results of the event are much closer to today's days than we did; think before. As Geyer said, the erosion of Eilean Deception is essential to our understanding of how to change the climate of the area over the centuries – especially because of volcanic pressure This level has influenced climate not just Antarctica, but also other areas of the southern Hemisphere.
"It is very important to be able to bring this type of fracture to understand the climate changes caused by volcanic breakdown – in this special case, at high current levels . "
