Abstract

Abstract. Bandar Lampung is one of the cities in Indonesia, which has the potential to land subsidence due to human activity or natural phenomena. However it is still lack of information and the study of land subsidence that ever made. This research used 15 SARs data in the intervening years from 2006 to 2011 were combined to produce the interferogram and then inverted by using SBAS algorithm. Based on data analysis, SBAS technique reliable enough to determine the deformation symptoms quick and accurately. However, some locations have indications of subsidence more than 5 mm/year, even the highest reaches more than 30 mm/year which is identified in the Campang Raya, Camang, Kangkung, Sukaraja, Bakung, and Beringin Raya. Subsidence that occurred is suspected caused by tectonic and human activity and is more likely to occur in the new area suffered by land conversion. Subsidence that occurred implications on damage to the building structure, the occurrence of tidal flooding in coastal areas, and landslides in hilly areas. Keywords: DInSAR, SBAS, subsidence, Bandar Lampung
