Sinkholes on receding Dead Sea shore mark 'nature's revenge'

A spectacular expanse of water in the desert, flanked by cliffs to east and west, the Dead Sea has lost a third of its surface area since 1960.

The blue water recedes about a metre (yard) every year, leaving behind a lunar landscape whitened by salt and perforated with gaping holes.

The sinkholes can exceed 10 metres (33 feet) in depth and are a testament to the shrinking sea. Receding salt water leaves behind underground salt deposits. Runoff from periodic flash floods then percolates into the ground and dissolves the salt patches. Without support, the land above collapses.

At the Ein Gedi thermal baths, the roughly three kilometres (two miles) of rocky sand that now separate the spa from the shore are dotted with holes and crevices.

Further north, a whole tourist complex has turned into a ghost town, disfigured by craters and enclosed in fences. The pavement is gutted, the lampposts overturned, the date plantation abandoned.

They reflect human policy that has literally decimated the flow of water into the Dead Sea. Both Israel and Jordan have diverted the waters of the River Jordan for agriculture and drinking water. Chemical companies have extracted minerals from the seawater.

Climate change further accelerates evaporation. In Sodom, Israel, southwest of the Dead Sea, the country's highest temperature in over 70 years was recorded in July 2019 -- 49.9 degrees Celsius, or nearly 122 Fahrenheit.

Gavrieli said the Israel Geological Institute is monitoring the formation of sinkholes from space but it is not an exact science.

He said they are certainly "dangerous" but also "magnificent."

"It has potential to become a tourist attraction, if you're willing to take the risk on one hand and if insurance issues are clear," he said.

Much too perilous, answers Gidon Bromberg, Israeli director of the NGO EcoPeace, for whom the sinkholes are "nature's revenge" for "the inappropriate actions of humankind".

"We will not be able to bring back the Dead Sea to its former glory," he said. "But we are demanding that we stabilise it."
