Abstract


The purpose of this study is to determine the type and distribution of volcanic rocks both laterally and vertically and to analyze the potential hazards of the Karaha-Sadakeling Volcanic Complex. Volcanostratigraphically, the volcanic evolution from old to young is Cakrabuana Crown, Sadakeling Crown, Ewaranda Crown, and Talagabodas Crown. The recognizable landforms are crater traces, volcanic cones, lava flow ridges, and alluvial plains. The north-south oriented volcanic cone morphology of the study area parallels an approximate major fault that passes between the Cakrabuana Complex to the northeast, and the Karaha-Sadakeling Complex. The northern part is dominated by Sadakeling Crown volcanic deposits, the central part is composed of Ewaranda Crown deposits, and the southern part is dominated by TelagaBodas deposits. The magmatic evolution shows the process of magma assimilation and mixing with primitive magma. Potential volcanic disasters can include pyroclastic fall, pyroclastic flows, and lava flows. Primary eruptions are inferred to originate from Karaha Crater, which exhibits ongoing volcanic activity.
