Short summary
The bedrock of the Ebro Valley consists of soluble geological formations of evaporites. The subsurface dissolution of these rocks makes this area particularly prone to the development of sinkholes. These show subsidence that causes damage to man-made structures. The article focuss on the subsidence detected along railways that traverse sinkholes. DInSAR analysis may help in the identification of subsiding sectors of railway tracks that may compromise the safety of travellers.
