The spectacle of explosive volcanic activity has always struck us with a sense of fascination and awe. Stories of the last days of Pompeii and Herculaneum, the massive eruption of Krakatau, and more recently the destruction wrought by Mount St. Helens in Washington and El Chinchon in Mexico have captured the public imagination. This atlas examines the aftermath of such events by looking at the …
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.
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,…

The past 25 years have been vast expansion in the field of igneous petrology to accommodate a wide range of new information from both the Earth and other terrestrial planets. This has made the subject far more interesting, but has also resulted in a marked increase in both the amount and the degree of specialization of the available literature.

Gunung api Gamalama merupakan Gunung api strato dengan tinggi puncak 1715 meter dan berada pada zona penujaman celah Sangir-Halmahera. wilayah ini merupakan zona penujaman yang cukup aktif yang dikenal dengan Punggungan Mayu.
Gunungapi Talang adalah salah satu gunungapi yang terletak di Sumatera Barat. Letusan megmatik terakhir terjadi pada tahun 1883. Letusan terakhir berupa letusan abu terjadi pada tahun 2005. Letusan pada tahun 2005 tersebut terjadi beberapa hari setelah gempa tektonik di Mentawai.
A study of the product of hydromagmatic activity and their associated xenoliths has been made on the recent volcanic centres on the island of Flores and Faila, in the Azores, in order to define the geothermal context.
Kompleks Volkanik Ijen berada di Kabupaten Banyuwangi, Jawa Timur, Indonesia, terdiri dari kaldera besar dengan luas 252 km, yang di dalamnya terdapat lebih dari 15 pusat erupsi. Diantara pusat erupsi tersebut, Kawah Ijen merupakan satu-satunya pusat erupsi yang masih aktif.
