Characteristics of Muria Vulkanism and Tectonic Impact at Development of Nuclear Reactor in Muria, Central Java

Indonesia is included in the country with the presence of thorium as nuclear fuel. Proposing the construction of a nuclear reactor in the Muria peninsula area has long been proposed but until now development has not yet been carried out. This research provides the latest recommendations regarding the history of eruptions, the characteristics of magma and the effects of volcanism and tectonics found in Muria Volcano located in the northwest of the nuclear reactor construction area by using library study methods, morphological analysis, field observation, petrographic analysis and geochemical studies. Young Muria vulkanism was produced in 320 thousand years ago with no detectable volcanic activity since human life with maar Bambang presence that older than young Muria volcano. The characteristics of magma were ultrapotasic series magmas in the middle-base lava series and the calc-alkaline potassic group or in the shoshonitic series which come from cooling magma that contact with ground water so that it usually produces phreatic eruptions but does not produce magmatic eruptions in the near future. Indications of faults in the Muria Volcano which is predominantly northeast directed by active tectonics because it is young so that tectonic earthquake hazards are most likely to occur
