In the later summer, 1981, the international symposium on “Arc Volcanism” was held in Tokyo and Hakone under the sponsorship of the volcanological society of Japan and the International Association of volcanology and chemistry of the Earth’s Interior (IAVCEI). More than 400 scientists attended the symposium and about 220 papers were read during the main session from August 31 through Sep…
This study was conducted in a joint project on physical volcanology between Gadjah Mada University Yogyakarta, Indonesia and the Institute of Geophysics, University of Stuttgart, Federal Republic of Germany.
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.
