In this northern region, land decline every year. One of the causes of land subsidence in Jakarta is excessive exploitation of ground water.

In this study, land subsidence data were taken using leveling, InSAR, and GPS methods in the period of 1925-2015.

After getting the results of the map of interpolation of sea water intrusion data and land subsidence, the authors created a grid to calculate the amount of land area and determine the land use affected by the two phenomena. Correlation obtained is that if there is sea water intrusion then there is land subsidence, but if there is land subsidence, it is not certain that the sea water intrusion will occur. The area affected by land subsidence and seawater intrusion is approximately 336 km2. text
