Abstract

ABSTRACT : Land subsidence is a decrease in ground level relative to some reference points. The phenomenon of subsidence is experienced by many big cities of the world and Indonesia. Monitoring of land subsidence in Bandar Lampung is done by integrated method, that is InSAR, and microgravity. From InSAR analysis with SBAS algorithm, from 15 datasets of ALOS-PALSAR between 2006-2011, there are indications of land subsidence in Bandar Lampung, with speeds above 5 mm / year, and highest 30 mm / year, and enlarged in the Gulf Coast Lampung. Land subsidence correlates with the existence of Panjang-Lampung Fault. Low anomaly of microgravity correlated with subsidence in the coastal part of Lampung Bay. These preliminary results need to be reinforced by other analyzes, so that land subsidence and its characteristics can be mapped properly and sustainably. Keyword : land subsidence, InSAR, Mircogravity, Bandar Lampung
