Present-day deformation of Agung volcano, Indonesia, as determined using SBAS-InSAR

Based on ALOS PALSAR images, time series deformation fields of the Agung volcano area were obtained using SBAS-InSAR in 2007–2009. The time series deformation showed obvious inflation around the Agung volcano area, which was positively correlated with time. We modeled the cumulated deformation inter...

description Based on ALOS PALSAR images, time series deformation fields of the Agung volcano area were obtained using SBAS-InSAR in 2007–2009. The time series deformation showed obvious inflation around the Agung volcano area, which was positively correlated with time. We modeled the cumulated deformation interferogram based on Mogi point source and vertical prolate spheroid source. The deformation model indicated that the vertical prolate spheroid model fit the observed deformation reasonably well. The magma chamber was located beneath the center of the volcano at a depth of approximately 5 km beneath the summit.
