This research is focused to the basic concept and procedures to monitor cinder cone deformation of Galunggung Volcano using Terrestrial Laser Scanning (TLS) method. Deformation monitoring which is usually done using point wise approach cannot fully interpret the deformation zone. This can be overcome by the use of TLS technology. Nowadays, there are only a few numbers of researches about volcano deformation using TLS, and consequently, the problems that may probably arise in this monitoring are still unknown. This research itself is addressed to answer potential problems. <br /> <br /> <br /> <br /> <br /> Methodology used in this research consist of literature study, survey planning, acquiring data, TLS data processing, and comparison of 3D dimension to interpret cinder cone deformation from two separate observations, on April 2012 and September 2012. Three-dimensional model of these two observations are then compared to obtain the deformation vector values and cinder cone surface volume. The final results obtained from this research are the volume estimation of the first and the second observations, and also the deformation range, which are 21635.19 m3, 21513.15 m3, and 2.6 cm, respectively. <br /> <br /> <br /> <br /> <br /> The result of 3D morphology modeling using TLS can be applied to mapping and to monitoring the cinder cone deformation of Galunggung Volcano. The modeling result showed that deformation occurs during the period of April to September 2012. Nevertheless, accuracy of the model is degraded by the inconsistency of object surface due to vegetation in the observed area. Values of the estimated deformation vector are larger than those obtained from GPS. These can be caused by the difference of environmental condition during the data enquiry and the methods used between the first and second observations. As the conclusion, the result of this research can be used for disaster mitigation and to figure out the problems that can arise in any volcano deformation monitoring using TLS.
