Short summary
Sinkhole formation and post-collapse deformation in the Solotvyno salt mining area was studied where the salt dissolution due to water intrusion poses a significant risk. Based on a Sentinel-1 data set, remarkable surface deformation with a maximum rate of 5 cm/yr was revealed, and it was demonstrated that the deformation process has a linear characteristic although the mining activity was ended more than 10 years ago.
