Observations of Deformation

Volcano number:357100
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:2002-2008
Inferred cause(s) of deformation:Surface deposits
Characteristics of deformation:

An Envisat interferogram from 2002-2008 showed subsidence at Lonquimay with a maximum rate of 2 cm/year (Fournier et al., 2010). The deformation was attributed to subsidence of the andesitic lava flow emplaced during the 1988-1989 eruption of Lonquimay.
