Researches on Active Volcanoes: Satsuma-iojima

火山研究解説集：薩摩硫黄島 (産総研・地質調査総合センター作成)

Preface

"Researches on Active Volcanoes: Satsuma-iojima" deals with the following points:

1. Summary of the geologic, geophysical, and geochemical data on Satsuma-iojima.
2. Explanation of individual data.
3. Unified interpretation of data and a model for the volcanic activities of Satsuma-iojima.

Prediction of activities of a volcano requires plausible model of volcanic phenomena. Various methods of observations have to be employed to get comprehensive data set to extract useful information related to volcanic activities (This is why the field of volcanology is composed of many research fields). One of the purposes of preparing this document is to show how the data encompassing many fields can be unified, and to promote understanding of the volcano, Satsuma-iojima.

Organization of this document

Satsuma-iojima and Mishima, the ferryboat, run by the local government

The document consists of two parts, summary version (in English and Japanese) and the full version (in Japanese).

The aim of the summary version is to give general idea and visual enjoyments of Satsuma-iojima to the general public, and describes simplified history and current activities of the volcano. For this purpose many photos and illustrations accompany with simple explanations.

The full version provides rich data and interpretations along with descriptions of measurements and analytical methods.

The summary version contains the following contents.

1. Introduction to Satsuma-iojima
2. Recent eruptions
3. History of the volcano
4. Volcanic gases and hot springs
5. Heat discharge
6. Underground structure
7. Magma system
8. Volcanic hazards

Using Devian GNU/Linux and Mediawiki, roughly equivalent environment for writing the article as are Wikipedia has been organized within AIST and its server, with the access restricted to the authors and the manager with password (Miyagi). Within the Wiki the list of contents and empty spaces were created (Shinohara and Miyagi) .Through repeated discussions, unified understanding among different authors were reached and person in charge of particular article was decided. The completed manuscripts were circulated among the authors belonging to the Geological Survey of Japan and text alterations were added if necessary. Finally, the data outputted with Mediawiki 1.6.10 were converted to hypertext using Perl script (Miyagi). The pages you are looking at use the style sheet and Javascript of Mediawiki, the source codes of which are open, based on GPL (Refer to [1],. [2], and [3]). (The style sheet was partially altered by Miyagi).
