Almost 156 years since 1847 until now, Guntur volcano, West Java, Indonesia, has been in a quite state. It is the most active volcano in Java after Merapi and Semeru not until 1847. The last two volcanoes are still very active until now. Guntur volcano lies on the edge SE of a NW-SE lineation of Gandapura-Masigit-Paruhpuyan-Kabuyutan-Guntur volcanic centers. It’s crater plugged with a volcanic neck of basaltic composition. The most recent eruption in 1847 produced tholeiitic basaltic lava flow reaching the Cipanas village of Tarogong town, 4 km SE of the crater. In its historic eruption times, Guntur volcano resulted volcanic collapses, series of pyroclastic flows, ash falls, and effusive lava flows. Differentiation of magmatic composition below Guntur volcano may be changed with the time. With such a danger of eruption and along time of quite state, it is obvious that Tarogong town would be immediately threatened by the incoming eruption in the future. For generations, people of Tarogong lacked of eruption experiences. Crisis-preparedness among the people and local government seems to be minimum. It could be a bizarre situation for them whenever the eruption occurred.Properly mitigation efforts and disaster management strategy could minimize the hazard of the incoming eruption.
