This book serves two basic purposes. First, it is an introduction to the clipper programming environment. If you sit and skim the first section of this book tonight, you will be creating clipper programs tomorrow morning. The second purpose of this book is to serve as your main reference whenever you need to look up a command or function. This book represents the most complete documentastion of…
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.
This thesis presents the results of a details trace element and isotope geochemistry study int the magma-genesis of volcanoes in the Adonara-Pantar Section (APS) of the East Sunda Arc in Indonesia, a setting where an oceanic island arc is colling with a passive continental margin.
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.
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.
