scientist have get a line " white smokers " — predominate common salt " chimneys " spewing cloud of shimmering fluid — on the bottom of the Dead Sea . And they seem to be harbingers of destruction .
The wedge pillars , which achieve up to 23 feet ( 7 meters ) in summit , could serve as an former warning of life - threaten sinkholes , which are common in the country .
The “white smoker” salt chimneys reach heights of up to 23 feet (7 meters) tall.
" To date , no one can portend where the next sinkhole will occur,“Christian Siebert , a hydroecologist at the Helmholtz Center for Environmental Research in Germany who led the subject field , articulate in astatement . " This make the white smokers an outstanding forecasting tool for locating country that are at risk of collapse in the near hereafter . "
The Dead Sea is a landlocked salt lake that frame in Jordan , Israel and the West Bank . Famed for its salt , the Dead Sea isalmost 10 time saltier than the ocean , and it ’s getting salty .

For the past 50 years , the Dead Sea has been wince rapidly due to local drouth and evaporation . This has also caused the weewee board to drop , constitute it increasingly difficult for neighboring countries to access groundwater resource , grant to theU.S. Geological Survey .
While investigate these military reserve , Siebert and a team of divers came across the recessed city of pearly - lily-white pillars , puke a shimmering fluid . Most were between 3 and 7 feet ( 1 to 2 metre ) in peak ( from the lake floor ) , although some reached an impressive 23 foot ( 7 m ) , and stretched up to 10 feet ( 3 thou ) in diameter .
" So far they are unique and never observed worldwide before , " Siebert tell Live Science in an email .
Upon investigation , it became clear that the shimmer liquid was groundwater from surrounding aquifers that had penetrated the thick layers of Strategic Arms Limitation Talks - robust rock on the Dead Sea floor . As this urine flows through the sway , some of the salt inside them dissolve , ensue in a highly concentrated brine .
However , even this salt - rich water is not as salty as the Dead Sea .
dissolve salinity in weewee increases its density , so the water in the Dead Sea is denser than this shimmering brine , cause the brine to rise " like a jet . "
" It looks like smoke , but it ’s a saline solution fluid , " Siebert articulate .
Because they have different compositions , the salinity in the saltwater crystallise out of the result the moment the two liquids mixture , forming slender pillar of salt that rise up from the sediment . These " white smokers " can grow by several inches every day . But in the Modern inquiry , publish Dec. 10 in the journalScience of The Total Environment , the team revealed that the lily-white smokers may also signal something more sinister .

Sinkholes are a major problemin the area around the Dead Sea . Over time , the wearing aside of the Strategic Arms Limitation Talks - rich rocks under the lake creates big surreptitious cavity . Out of nowhere , the thin stratum of stone above collapses , creating a gaping sinkhole .
For years , scientists have been trying to identify ways to presage when and where these dangerous sinkholes will emerge . Now , Siebert and colleagues have reveals that they often seem in areas with the white smoker . If the finding is confirmed , these predominate chimneys could be map across the lake floor to key the most vulnerable areas .
" This would be the only method acting to escort , and a extremely efficient one , for identifying regions at risk of imminent crash , " Siebert suppose .
