Observations of Deformation

Volcano number:273030
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR, GPS - campaign, GPS - campaigns, InSAR
Duration of observation:1992-1996 (GPS campaigns), 2007-2011 (InSAR)
Inferred cause(s) of deformation:Surface deposits, Subsidence of lava flows
Characteristics of deformation:

ALOS InSAR time series survey (2007-2011) reveals subsidence at a rate of 3.5 cm/yr over lava flows emplaced during 2006 on the SE flank (Morales et al., 2015).
No significant surface deformation was observed within the accuracy of the campaign GPS measurements (Vajda et al., 2012).
