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.
Telah lama Gunung Merapi menjadi pusat perhatian para ahli. Sejak zaman penjajahan Belanda, Gunung Merapi telah menjadi prioritas bagi pemerintahan colonial dalam usaha pemantauan gunungapi. Pada saat itu perhatian diarahkan ke Gunung Merapi hanya karena gunung ini mempunya aktivitas yang hamper berlangsung secara menerus.
The eminent volcanologist T.A. Jaggar in no way exaggerated the significance of volcanic phenomena when je stated that his conception of volcanicity was of a process which is everywhere at work within and beneath the earth’s crust. Today there are more than 500 volcanoes which are still active or at which activity has been recorded during historic times, while the number of extinct volcanoes,…
This , My Latest Book, is another experiment. After sixty years of volcanoes I have learned reversal of preconceived notions. Gradually I have learned a totally different approach. Shaler of Harvard was my inspirer, worker in the wonder of swamp and ice and sea beaches.
The chapters of this volume deal with dating, chronology, stratigraphy, volcanic activity, and with the impacts of volcanism on animals, plants, human populations, and the environment. Some of these chapters explain how such findings must be weighed against other cause that influence human behavior and survival, such as factors of social customs, climatic change, shifting biogeographic patterns…
The rapid growth of geothermal electrical generation in recent years has been accompanied by rapid growth in our knowledge of the behavior of reservoirs in their natural and exploited states. Good textbooks and literature surveys exist both for the earth sciences and for surface plant engineering.
The objective of any acoustical echo technique is the collection of information on the internal structure of a medium, avoiding destructive penetration. Examples of media which are being investigated intensively with acoustic waves are: the earths subsurface, transition zones of waterbottoms, human organs and tissues etc.
Sistem panas bumi Marana ditandai oleh manifestasi panas bumi di permukaan berupa mata air panas Masaingi, Marana, dan mata air panas Yompo yang bertemperatur 51°C hingga 91°C, bersifat netral hingga basa, memiliki nilai daya hantar listrik bervariasi mulai 660 µS/cm sampai 3190 µS/cm, dan berada pada elevasi 2 – 110 mdpl. Hasil analisis geokimianya memperkirakan bahwa fluida panas bum…
Kegiatan survei rinci di daerah panas bumi Nage, Provinsi Nusa Tenggara Timur dilakukan untuk mengidentifikasi peranan kontrol struktur geologi terhadap zona permeabilitas dan mengetahui zonasi mineral ubahan serta mengestimasi umur batuan atau proses hidrotermal yang terjadi, dalam kaitannya dengan pembentukan sistem panas bumi di daerah Nage, melalui pengamatan dan pengambilan conto di lapang…
