| Measurement method(s): | InSAR |
| Duration of observation: | 2007-2011 |

| Characteristics of deformation: |
A regional ALOS survey of Northern Andes Volcanoes found Cerro Auquihuato to be inflating at a rate of 1.8 ± 0.3 cm/year between 2007 and 2011 (Morales-Rivera et al., 2016). The deformation was modelled by a sill at 1 km depth opening by 10 cm, which the authors suggest could be either magmatic or hydrothermal in origin. |
