Soputan Volcano is one of the few basaltic volcanoes among 127 active volcanoes in Indonesia. It is part of the Sempu-Soputan volcanic complex located south of Tondano Caldera, North Sulawesi and commonly produces both explosive eruptions with VEI 2-3 and effusive lava dome and flow eruptions.
Upaya yang dilakukan dalam menghindari bahaya letusan gunungapi salah satunya adalah dengan melakukan pemantauan secara periodik atau berkala. Hal ini dimaksudkan untuk melihat besarnya pergerakan dan tingkat aktivitas dari tubuh gunungapi.
Akibat dari akitifitasnya pergerakan sistem sesar Sumatera menimbulkan fenomena alam yang destruktif, yaitu terjadi gempa di sepanjang lintasannya. Sistem sesar Sumatera juga merupakan salah satu sistem geser aktif terbesar di dunia. Ini menyebabkan wilayah Pulau SUmatera menjadi wilayah potensial jika terjadi gempabumi di kemuaidan hari. Selain itu, banyaknya gunung api di Indonesia menjadika…
Citra penginderaan jauh sangat penting dalam bidang vulkanologi, karena dapat memberikan data dengan cepat, mudan dan murah, sehingga sangat membantu sebagai pengumpul data geologi mauun vulkanologi. Dengan citra penginderaan jauh, dapat dengan mudah menentukan bentuk kawah, penyebaran litologi, penentuan daerah ahaya sementara dan daerah aman. Hasil interpretasi sangat tergantung dari pada ti…
Kelimutu is a stratovolcano that has three crater lakes containing exotic fluids. This study presents the analytical results describing the chemistry of each lake, interprets the chemistries in terms of water-rock interactions and volcanic fluxes, and derives a physical lake model that delineates the parameter-window for volcanic crater lake existence.
This study deals with the massive Elvaberget sulphide deposit, in the southern part of the central skellefte district. The ores as well as the surrounding rocks and alteration zone were studies.
Ce travail a pout objet 1 etude de la circulation des eaux soterraines dans formations volcaniques pas methode PS.
The first is the present statement of the volcanological application ot the SP method. This method is typically used detect hydrothermal zones which exist when two conditions are filled up; presence of a heat source and of a zone with high permeability.
This study concern the quaternary geology, geomorphology and sedimentology of the intramontane Bandung basin, West - Java, Indonesia. A comprehensive analysis of the sequence of lacustrine, alluvial and volcaniclastic sediments in the basin form the basis for a reconsstrution of the Late Quanternary geologic and morphologic evolution of the Bandung basin area and for an evaluation of the geolog…
