Laporan Pendahuluan Penyebaran Lava G. Batur (Bali)

Gunung Batur telah meletus poda tgl.23/1-1968. Aliran lava mulai mengalir pada tgl.30/1-1968 dan berhenti pada tgl.15/2-1968.Ternjata lava tsb. mengalir dari lobang letusan 1963 komplek I,menudju kedjurusan selatan dan berhenti pada ke-tinggian k.l.1100 M dari permukaan lout; pondjang rata-rata 1.930 M dan lebar rata2 540 M. Lava ini mengalir diatas lava 1963 dan menjeretnja; kemudian nelebar s…

Fundamentals Of Physical Volcanology

Fundamentals of physical Volcanology is a comprehensive overview of the processes that control when and how volcanoes erupt. Understanding these processes involves bringing together ideas from a number of disciplines, including branches of geology, such as petrology and geochemistry; and aspects of physics, such as fluid dynamics and thermodynamics.

Global Volcanism 1975 - 1985

Volcanism is one of nature’s primal spectacles. It commands our attention, whether for its awesome power, its danger, or its beauty. The years 1975-85 brought dramatic examples of volcanism – from the 1980 blasts of Mt. St. Helens, through the continuing lava river of Hawaii, to the tragic eruption of Colombia’s Nevado del Ruiz in 1985 and these have been abundantly documented by the news…

Volcanology and Geochemistry of Newer Volcanis from Portland area, Western Vi…

The volcanic rocks mainly consist of lava flows and pyroclastic deposits that are exposed at the bridgewater, Nelson and Grant volcanis compoxes. Yhe pyroclastic deposits resulting from phreatomagmatic eruption varu in physical characteristics that are likely caused by fluctuation of magma/water ratio during interaction.

Evolusi Magmatik Komplek Kaldera Rinjani, Lombok, Nusa Tenggara Barat, Indone…

Kompleks Kaldera Rinjani (3.276 mdpl) berlokasi di Pulau Lombok, Nusa Tenggara Barat. Kompleks ini mempunyai puncak dan kaldera jenis runtuhan berukuran sekitar 6x7km sebagai hasil letusan Gunungapi Rinjani Tua pada abad ke-13. Tujuan penelitian ini untuk mengetahui karakteristik magma dan evolusi magmatis Kompleks Kaldera Rinjani.

Calc-Alkaline Lavas From The Volcanic Complex of Santorini Aegean Sea, Greece

This thesis presents the results of a petrological-geochemical and stratigraphic study of the calc-alkaline lava from Santorini, Aegean Sea, Greece. The volcanic complex of Santorini consists of seven eruption centres, of which some have been active contemporaneous.

Behavior of Volatiles in Arc Volcanism ; Geochemical and Petrologic evidence …

The transport of chemical elements by uprising magma is one of the fundamental processes by which material is recycled through subduction along convergent plate-boundaries. Obtaining quantitative information on the mass balance of volatile elements is hampered by their complex behavior in magmatic systems.

Gunung Sinabung adalah gunung berapi tipe strato, yang terletak di Kabupaten Karo, Prov. Sumatera Utara, Indonesia. Gunung ini termasiuk kedalam gunung berapi tipe A setelah terjadi erupsi pertamanya setelah lebih dari 400 tahun tidak aktif, yaitu pada tahun 2010, yang kemudian kembali aktif pada tahun 2013. Erupsi dimulai dengan fase freatik, berganti menjadi freatomagmatik, lalu erupsi afusif…
