Research Abstract |
We have established the measurement procedure of a field absolute gravimeter(Micro-g LaCoste A10) which has been rarely utilized for the subsidence studies so far, and have successfully detected the gravity changes due to the ongoing land subsidence by conducting the repeated measurements in Jakarta and Bandung, Indonesia. In addition, comparing the gravity data with those of the recent space geodetic techniques such as GPS and InSAR(Interferometric Synthetic Aperture Radar), we revealed that the land subsidence in Jakarta was probably due to the excess pumping of the groundwater.
