Sangay

Observations of Deformation

Volcano number:352090
Region:
Country:Ecuador
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:2007-2011
Inferred cause(s) of deformation:Surface deposits
Characteristics of deformation:

During a regional ALOS survey of Northern Andes Volcanoes, Sangay was found to have consistent motion towards the satellite on the southwest flank at 1.3 ± 0.4 cm/year and away from the satellite on the southeast flank at 4.3 ± 0.4 cm/year (Morales Rivera et al., 2016). Given the satellite look direction, the measured motion is attributed to downhill motion of the steep flanks of the volcano by 3-5 cm/year
