Gedamsa (also known as Gedemsa or Gadamsa) volcano has been observed using InSAR data between 1997-2000 and 2003-2010. However, the study, Biggs et al. (2011) found no deformation at the volcano during this time.

Interferograms used in the analysis of deformation. Each fringe represents 2.8 cm of displacement in the satellite line-of-sight (Biggs et al., 2011). The summit of the volcano is shown by a black dot, as reported by the Smithsonian Database (Siebert and Simkin, 2002).
