| Volcano number: | 352090 |
|---|---|
| Region: | South America |
| 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 |
