Observations of Deformation
Volcano number: | 352080 |
---|---|
Region: | South America |
Country: | Ecuador |
Geodetic measurements? | Yes |
Deformation observation? | Yes |
Measurement method(s): | InSAR, GPS - continuous, Tiltmeter |
Duration of observation: | 2003-2009 (Envisat InSAR), 2007-2009 (ALOS InSAR), 2010 - present (GPS, Tilt) |
Inferred cause(s) of deformation: | Magmatic |
Characteristics of deformation: | Following the start of a long term eruption in 1999, persistent scatterer InSAR between 2003 and 2009 showed large scale uplift centred on Tungurahua, with a peak rate of 8 mm/year (Chapenois et al., 2014). The deformation source was modelled as magma emplacement in a storage zone at 11.5 km depth at a rate of 7 million m3/year. |
