Abstract

The underground salt mine in Tuzla, Bosnia and Herzegovina (BiH) has caused one of the most serious ground subsidence problems in Europe. The mine was closed from 2006-2007 by means of filling the salt mine rooms with water. However, the subsidence still continues over some parts of the city. This paper presents the recent measurement results together with the previous results, i.e., 2004-2007 by GNSS, 2007-2013 by GNSS and geodetic surveys, and 2014-2019 by GNSS and DInSAR. The time transition for the subsidence obtained by DInSAR shows a good agreement with the monitoring results by GNSS. It is found that the subsidence in Tuzla is still on-going at a rate of 1-4 cm/year in the eastern area of the salt deposit. In a hilly section of the eastern area, a dominant horizontal displacement was detected by GNSS surveys. It is concluded that the combination of SBAS-DInSAR, GNSS, and geodetic surveys will be effective for monitoring both subsidence and landslide behavior.
