Volcano number: 352030
Region: South America
Country: Ecuador
Geodetic measurements? Yes
Deformation observation? No
Measurement method(s): InSAR
Duration of observation: 2007-2011
Inferred cause of deformation: []
Characteristics of deformation:

Preliminary ALOS results found Antisana had periods of both inflation and deflation between 2007 and 2008, coincident with a period of high LP seismic actiity (Mothes et al., 2008). However, a regional ALOS survey of Northern Andes Volcanoes found no deformation at Antisana between 2007 and 2011 looking at a larger dataset (Morales Rivera et al., 2016). The preliminary deformation observations are therefore likely to have been atmospheric noise.
