Situe dans la partie est de Java, le Kelut est l'un des volcans les plus regulierement meurtriers d'Indonesie. Une trentaine d'eruptions y ont ete recensees. La derniere, en 1990, est l'objet principal de ce travail. Reconstitution de l'histoire geologique du Kelut. La reconnaissance de 3 stades dans l'evolution du volcan est nouvelle; elle se fonde sur des changements morphplogiques et structu…
Caldera forming eruption is on of the important phenomena that caused direct huge damage of global impact not only for a short time but moreover for long periods. There have been three big caldera forming eruption in Indonesia within a period of 1000 years BP that affected global climate change, such as Rinjani (1257 AD), Tambora (1815 AD) and Krakatau (1883 AD).
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.
Mass and energy balance allow magma transport within volcanoes to be quantified. Thus work used microgravity and height data and their variation to interpret volcanic. activity. An international comparison of absolute and relative gravimeters (at BIPM, serves) and a set of measurements in a adjustable pressure-temperature chamber revealed the performances and the limits of the Scintrex SG3-M me…
Sinabung Volcano is located in North Sumatra with 2,460 meters high above sea level. This volcano was originally classified as type B volcano, but then classified as type A volcano because is is re-active on 29 August 2010.
Kami mengestimasi struktur kecepatan tiga dimensi gelompabng P (Vp), kecepatan gelombang S (Vs) serta rasio Vp/Vs di bawah permukaan Gunung Sinabung, Kabupaten Karo, Sumatera Utara. Gunung Sinabung termasuk ke adalam tipe B, yaitu gunungapi yang tidak ada aktivitas vulkanik lebih dari 400 tahun. Aktivitas kegempaan Gunung Sinabung mengalami peningkatan kembali pada Juli 2013, diikuti serangkaia…
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…
Mount Merapi, island are volcano located in the center of Java (Indonesia), lies upon the remnents of a volcano older than 400.000 years called Pre-Merapi. Sensu stricto Merapi is a very young volcano characterised by a rapid edification. Its history is divided into four periods (ancient, Middle aged, Recent and Historical Merapi).
Gunungapi Soputan merupakan salah satu gunungapi aktif di Sulawesi Utara. Pada 4 Januari 2016 terjadi erupsi eksplosif yang mengakibatkan 14 desa tertutup abu vulkanik. Pada penelitian ini dilakukan analisis data gempa vulkanik G. Soputan berupa gempa vulkano-tektonik, low frequency dan vulkanik hbrid, untuk menganalisis pergerakan magma dan mekanisme fokal. Pengolaha n dilakukan untuk menentuk…
