Abstract

Gamalama volcano is an active volcano located in Ternate Island. Besides volcanic ash and lava, lahars is one of the volcanic hazards threatening the Island. One of the rivers being susceptible to lahars flood is Barangka (River) Tugurara. The downstream of this river is very densely populated creating high risk to the community. According to this issue, therefore it is important to conduct physical assessment of the Barangka. The research uses field survey and Analytic Hierarchy Process (AHP) methods. The data used for this research including geomorphological and topographical data, river width, rainfall intensity, slope, and land use. The result shows that volcanic hazards of the Barangka may be classified into high and medium levels. The high level of volcanic hazards is located in the break of slope caused by a meeting point between the two flows of volcanic material. The medium level of volcanic hazards is located in the downstream area caused by sedimentation of volcanic material.
