Melalui telaahan yang dilakukan berdasarkan pengalaman dan pengetahuan ilmu kegunungapian para ahli geologi gunungapi di lingkungan Direktorat Vulkanologi khususnya yang berada dalam kelompok Standardisasi Penyusunan Peta Geologi Gunungapi, akhirnya Satuan Stratigrafi Gunungapi Indonesia dapat disusun.
Identifikasi dan kajian terhadap terhadap kondisi lingkungan geologi yang memiliki keragaman geologi yaitu komponen (bentukan) geologi dengan keragaman batuan, mineral, bentangalam, dan proses yang membentuknya sepanjang waktu geologi dapat memberikan perlindungan terhadap suatu lingkungan geologi yang dapat dijadikan kawasan cagar alam geologi.
Tout commence il y a quatre millards et demi d’annees, dans un escape de vide de notre galaxie, quand un immense nuage chaud de gaz et de poussieres se cree, puis commence a tourner lentement et a se contracter pour donner naissance a une nebuleuse.

The lateral blast, which lasted only the first few minutes of a 9 hour continuous eruption, devastated more than 150 square miles of forest and recreation are…
Los Alamos National Laboratory, with support from the U.S. Department of Energy, has been developing geothermal energy technology for nearly 20 years. The technology and experimental verification concepts developed by the Laboratory’s Hot Dry Rock Program have demonstrated tremendous potential for what is now known as heat mining- the creation of a man-made heat-exchange system in hot, fractu…
Ketika Gunung Tambora di Indonesia Meletus pada 1815, terlepaslah gelombang cuaca ekstrem yang paling merusak yang pernah disaksikan dunia dalam ribuan tahun. Awan debu sulfat gunung api itu menyelubungi bumi, menurunkan suhu, serta menganggu sistem-sistem cuaca utama selama lebih dari tiga tahun.
Volcanic activity is one of the main agents responsible for shaping the landscape, environment and climate of planets and moons. On Earth, volcanic eruption can also have catastrophic consequences for human society.
The purpose of the present volume is to overview the state-of-the art in tsunamiite sedimentology and to point out any problems and subjects that need additional investigations, as well as to provide an insight into the direction and potential for future researches.
Sebaran batuan gunung api dan sedimen asal gunung api sangat luas, baik di Indonesia bagian barat maupun Indonesia bagian timur. Akan tetapi, terdapat permasalahan dalam batuan gunung api dan sedimen asal gunung api, salah satunya adalah jarang dijumpainya fosil indeks penunjuk umur dan lingkungan pengendapan.
Most of the Earths mountains, valley and plains have been slowly sculpted by uplift and erosion ever that last million years, and these, in turn, have formed from other landscape long vanished. Volcanoes though, operate on a different time scale.
