Abstract

Mount Sinabung is one of active volcano in Karo North Sumatra Indonesia. Before 2010, Sinabung was categorized as a dormant volcano. After eruption that happened on August 29, 2010, Sinabung increased its level as active volcano. The eruption of Sinabung occured again in September 2013 until now that has not stopped its activity. The research purposes are to analyze the characteristics of volcanic hazard of Sinabung Volcano eruption in Karo and to know the distribution of the characteristics of volcanic hazard of Mount Sinabung. The characteristics of volcanic eruption hazard were analyzed based on geomorphological characteristics because volcanic eruption is one of geomorphological process. Moreover, the geomorphological characteristics were analyzed based on satellite image interpretation, geological map interpretation, and field survey. Delineation of volcanic hazard and data analysis used Geographic Information System (GIS). Moreover, the research results were analyzed as descriptively and spatially. The results show that the volcanic hazard characteristics of Sinabung consist of primary and secondary hazards. The primary hazards of Sinabung eruption are pyroclastics flow (hot clouds), pyroclastic fall (volcanic ash and rocks), and lava flows. Generally, the primary hazard threatens the eastern, southern, southeastern and southwestern regions of Sinabung Volcano. Meanwhile, the secondary hazard of Sinabung eruption is the lahar flow along the Lau Borus River and other rivers which disgorged at Mount Sinabung.
