Studying landslide displacements in the ciloto area (Indonesia) using GPS surveys

The paper presents and discusses results and performance of GPS surveys in Ciloto, a well known landslide prone area in West Java (Indonesia). Five GPS surveys involving 17 GPS points have been conducted during the period 2002-2005. The results of the GPS surveys show that the magnitude of land movements in the study area vary from centimetres to decimetres, depending on the location and observation seasons. The study also suggests that to confirm the displacements of the GPS points and to infer the type of landslide, GPS estimated displacements should be tested and analysed with different methods.
