“…The difference of 35 m between the Dead Sea level in the 1960s and the 2010s is due to two factors: water diversions upstream that are responsible for about 66% of the drop in water, and siphoning of the brine by mineral companies, which represent 33% (Tahal Group and GSI, 2010). In the early 1960s, with great geotechnical difficulties, the Israeli Dead Sea Works (DSW) developed a salt evaporation pond system over the western part of the 402 m bMSL southern basin (Closson and Abou Karaki, 2014a). Fifteen years later, APC finalized a similar infrastructure on the eastern Jordanian side ( Figure 1; dike1 and saltpan "SP-01").…”

In many areas of the world, subsidence related to the lowering of the water table is modifying the landscape and provoking costly environmental hazards. We consider the Dead Sea (the Earth's lowest lake) as a model. Its water level was 395 m bMSL in the 1960s. Due to water diversions in the catchment area, as of 2016, the level has dropped to about 430 m bMSL. Here, as in other parts of the Anthropocene world, from China, to Iran, to Turkey, to Canada and the United States, consequences of human interventions are rapidly modifying the environment. Aggressive geomorphic processes leading to accelerated degradations are taking place and affecting landforms and infrastructures. In Tectonic terms, the lake is a pull‐apart basin resulting from the motion of the Dead Sea Transform fault. Since the 1960s, a slice of brine of about 35 km3 has been lost. The water table is dropping more rapidly in the lake than in the coastal zone creating an ever‐increasing head difference. Consequently, groundwater moves towards the sea to compensate for the imbalance, provoking the reactivation of the area's paleo‐channels with subsidence, sinkholes, and landslides. Since the 1980s, industrial‐touristic infrastructure has covered newly emerging lands in geomorphic hazards‐prone areas of the coastal zone. Time series analysis of high to very high resolution visible/radar satellite images acquired from the 1970s to present, revealed major landscape evolution. Such dynamic systems prevailing in recent decades permitted the study of human/environment interactions to help minimize their effects. Major deformations of an industrial dike were analysed and quantified. The results underline the necessity in the Anthropocene of careful analysis of relevant data sources acquired before and during subsidence, particularly in karst topography zones and prior to the development of major human activities in economically appealing environments around the world.

The procedure for evaluating the susceptibility to natural and anthropogenic sinkholes is aimed at contributing to mitigate the risk from the most common geohazard in karst. It develops from the identification and geographical location of the caves, and then proceeds with the speleological survey, before characterising the caves in terms of geological-structural data (highlighting all the existing discontinuities in the rock mass, of both stratigraphic and tectonic origin), and of all the features related to occurrence and development of instability processes. Laboratory tests and monitoring are also mentioned as further possible steps of the analysis. Eventually, the procedure results in a zonation depicting the sectors most prone to development of sinkholes
