The choice between 2-pass or higher order pass D-InSAR algorithms to separate the displacements component of the interferometric phase represents a trade-off between the necessity to re-sample and coregister a low resolution external DEM to SAR acquisition geometry, and the necessity to unwrap an interferometric phase which contains the topographic component. Majority of works carried in this domain prefer the use of 2-pass D-InSAR algorithm. In this paper, reliable results are obtained by implementation of a 3-pass differential interferometric processing chain to estimate the displacements caused in Perugia region, Italy, by the earthquake which occured on 30.10.2016.
