Assessing sinkhole activity in the Ebro Valley mantled evaporite karst using 1 advanced

19 Sinkholes in karst areas may cause subsidence damage in transportation infrastructures, 20 demolition of buildings and even the loss of human lives when they occur in a 21 catastrophic way. Differential Interferometry (DInSAR) is a promising technology for 22 detecting and characterizing sinkholes, as well as for reducing the associated risk when 23 combined with other sources of data such as a sinkhole inventory. In this work, the 24 usefulness of InSAR techniques and data for sinkhole risk management have been 25
