Abstract

Gayo plateau, Aceh-Indonesia is one of an urbanized area affected by tectonic phenomena due to the presence of the Great Sumatran Fault, which extends from the north in Aceh to the south in Lampung. This area was affected by strong seismically phenomena (Gayo plateau earthquake on 2 July 2013, Mw 6.3) which induced landslide and deformat ion. InSAR applicat ion using Sent inel-1 times series with Terrain Observation Progressive Scans (TOPS) mode has permitted a short acquisition repetit ion cycle, an extremely large coverage, a high spatial resolution for the covered area and a small baseline separation part icularly suited for interferometry applicat ion. All of those characterist ics suggest intensive exploitation of these data through the use of the interferometry technology and in particular the stacking interferometry for monitoring ground surface displacement. A Persistent Scatterer and Quasi PS technique which was used in this research. The results of Persistent Scatterer, Quasi PS, and the combinat ion of both techniques with ascending and descending of Sentinel-1A were presented in this paper. The SARPROZ software which PS and Quasi-PS technique seems to be the best candidate for this applicat ion relative to the morphology and large extension of the Lut Tawar Lake in the Gayo plateau. We have been collecting SAR imaging over the Lut Tawar Lake since 2017. This allows taking into measures for seismic hazard mit igation widely in the Gayo plateau.
