Detecting the Damaged Areas Caused by Sinabung Volcano Eruption During 2013-2016 Using Landsat-8 Multitemporal

After inactive for centuries, in 2013 Sinabung Volcano active again with the enormity eruption that release a hot cloud, lava and pyroclastic flows. The eruption is said to have claimed lives and destroyed human settlements, agricultural land and existing infrastructure, particularly on the slopes of the south, southeast and east. During the period from 2013 to mid 2016, this volcano is still experiencing some major eruption, so it is possible having the affected area more extensively. This study aims to detect the damaged areas caused by the eruption in the period 2013 to 2016 by using a medium resolution satellite data, Landsat latest generation, the Landsat-8. The data used is a pair of multitemporal imagery, ie the first is recorded data before the eruption and second is data recorded during or after the eruption. The method is performed include the radiometric correction, land cover supervised classification, detection the areas affected by the eruption and GIS analysis to determine spatial-quantitatively the damages, namely in the context of the extents of each type of landcover that having damaged or destroyed by the eruption. The results showed that the medium resolution data Landsat-8 is very useful for use in detecting and mapping the damaged areas caused by the eruption of a volcano
