Geodetic measurements (e.g. Spirit Leveling, GNSS and InSAR) have clearly measured the land subsidence in many parts along northern coast of Java Island Indonesia. The impacts from the subsidence (e.g. problems on infrastructures, wider expansion of flooding, tidal inundation, etc.) are significantly appeared in certain places and already concluded as ecological disaster. Since mostly the land subsidence are located in cities lying on sediment area like Jakarta, Pekalongan, Semarang, Demak, and Surabaya where consumption of groundwater is very huge, in this case the typical of subsidence might be categorize as anthropogenic land subsidence. Nevertheless in order to make sure this typical, in this case the investigation on the others factors like the tectonic influence is necessary (e.g. as key for appropriate of adaptation or mitigation from disaster).This paper will highlight the investigation by using GNSS dataset in order to see the tectonic influence to the anthropogenic subsidence along northern coast of Java Island. Our preliminary result shows relatively lack of tectonic influence to the anthropogenic subsidence around the investigated area.
