|Region:||Africa and Red Sea|
|Duration of observation:||1996-1997, 2005 - 2010|
|Inferred cause of deformation:|
|Characteristics of deformation:|
Atzori et al (1999) processed ERS 1/2 InSAR data from 1996-1997 to look at Erta Ale, but report no deformation. In addition, Pagli, et al. (2014), for the purposes of investigating regional velocity fields, has looked at Envisat InSAR data (2005 – 2010) covering this volcano. They also report no deformation.
