Characteristics of deformation:

InSAR data between 1997-2000 (ERS) and 2004-2010 (ENVISAT) have been processed by Biggs et al. (2011). They found no deformation at this volcano throughout these times.

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).
