Sahand

Observations of Deformation
Explore Sentinel-1 imagery

Volcano number:	232001
Region:	Middle East and Indian Ocean
Country:	Iran
Geodetic measurements?	Yes
Deformation observation?	Yes
Measurement method(s):	InSAR
Duration of observation:	2003 to 2010
Inferred cause of deformation:	Uncertain
Characteristics of deformation:	Shirzaei et al. (2012) present Envisat radar InSAR images from 2003 through 2010 at all Iranian volcanoes, using multitemporal interferometric analysis. The authors present evidence of time-dependent surface displacements at both Sabalan and Sahand volcanoes. The sources of the observed deformation is subject of ongoing research and no further detail is presented.
