Abstract：On the basis of the 6 JERS1 SAR images, the time series of deformation in Tengchong volcanic area were obtained by SBASDInSAR technique through separating the linear deformation phase, the nonlinear deformation phase, the atmospheric phase screen and the DEM residual error phase. Compared with the GPS measurement results, SBASDInSAR technique can detect the crustal deformation at the precision of subcm level. The deformation of the DanzhaGaotian fault is obviously different between the two sides,which may relate the chamber below. The deformation pattern of the Dayingshan area indicates that there is probably an buried fault underground.
