Abstract

Bandar Lampung is one of the cities in Indonesia, which has the potential to land subsidence due to human activities or natural phenomena. However,it is still lack of information and the study of land subsidence that was ever made. This research used 15 SARs data in the intervening years from 2006 to 2011 and was combined to produce the interferogram, and then, it was inverted by using SBAS algorithm. Based on data analysis, SBAS technique was reliable enough to determine the deformation symptoms quickly and accurately. However, some locations had 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 suspectedcaused by tectonic and human activities and is more likely to occur in the new area suffered by land conversion. Subsidence that occurred implies on damage to the building structure, the occurrence of tidal flooding in coastal areas, and landslides in hilly areas.
