Sinkholes at the Dead Sea have threatened tourists and forced Israeli (and perhaps Jordanian)authorities to close various facilities and cancel development plans to avoid these geologic hazards. These are not your typical Karst sinkholes. According to a recent AP article, they are caused by the erosion of salt deposits by fresh water as a result of the lowering of the water level.

At the end of the article is an interesting note that the World Bank is currently evaluating a proposal to replenish the Dead Sea by digging a $15 Billion canal from the Red Sea, about 100 miles away.
