ABSTRACT
On December 22, 2010, in Ocna Mures, a salt cavern collapsed and an approximately 7000 square meters crater was created on the terrain surface, after which the area adjacent to the collapse cone was affected. Following the redevelopement of the area adjacent to the collapse cone, a system of topographic tracking was implemented ,consisting of stability tracking landmarks. The purpose of this research consistes of monitoring the redeveloped terrain stability, of determining the horizontal and also the vertical distortion and the displacement parameters based on the data collected from the topographic monitoring. The research is also considering the prognosis of this phenomenon, in order to anticipate and to be able to prevent potential future collapses.
