The Hawaiian Islands are home to some of the most active volcanoes in the world resulting in a constant state of deformation. After 2005, deformation at the summit caldera of Kilauea changed from deflation to inflation before returning to the typically observed deflation. In 2007, new fissure eruptions occurred in the East Rift Zone as a result of dike intrusions. Interferometric synthetic aperture radar (InSAR) data from Radarsat and Envisat are used to generate source models for the deformation, and, using the small baseline subset (SBAS) algorithm, InSAR time series are created for this period. The results allow for analysis of the deformation patterns both spatially and temporally to better understand the dynamics of the magmatic system.
