Volcano number:	222060
Region:	Africa and Red Sea
Country:	Kenya
Geodetic measurements?	Yes
Deformation observation?	Yes
Measurement method(s):	InSAR
Duration of observation:	October 1997 - September 2000, 2003 - 2010
Inferred cause of deformation:	[]
Characteristics of deformation:	Between 1997 – 2000 one ERS interferogram measured 3 cm of subsidence (Biggs et al 2009). This signal was modelled as a penny shaped crack source geometry, with diameter of 5.5 km at a depth of 1.5 km. Robertson (2015) looked at ALOS interferograms between 2003 – 2010, but no deformation was recorded (within a 0.66 cm/yr deformation threshold).
