This dissertation explores the combination of Interferometric Synthetic Aperture Radar (InSAR) results with field data to provide additional constraints on the processes controlling deformation signals observed at Galeras volcano (Colombia) and Santorini volcano (Greece).
InSAR measurements during 2007-2008 at Galeras reveal a subsidence signal on its northeast flank. I model InSAR and gravity data to determine the best-fit parameters for the subsidence source and suggest this signa...Expand abstract
