     On the basis of ALOS PALSAR images, we extracted the time series of surface deformation field of Agung Volcano in Bali Island, Indonesia during 2007 and 2009 by SBAS-InSAR technique, and inversed magma chamber parameters based on the Mogi point source and vertical spheroid models. The results showed that： the interference of atmospheric delayed phase was severe in Agung Volcano area. Agtmg Volcano showed the up- ward deformation characteristic from 2007 to 2009, and kept positive correlation with time. Deformation model- ing indicated that the deformation obtained by vertical spheroid model matched very well with the InSAR-derived deformation, and the magma chamber was located at about 5 km beneath the volcanic edifice. From the deform- ation results derived by SBAS-InSAR, we should monitor the potential eruption of Agung Volcano.
