Geological Maps of Volcanoes (sorry, temporarily unavailable)

AIST (Geological Survey of Japan is a part of it) has provided geologic map of each active volcano in Japan with brief summary of eruptive history. From distribution of ejecta in the past, age of volcano, and its characteristic features, we could predict future activities to some extent. Every volcano has its individuality expressed in its mode of eruption, frequency of activity, and eruptive scale. The geologic map of volcanoes tries to show the individuality as if a curriculum vitae of the volcano. It would be useful for prediction of eruption, change in eruptive mode etc. It also gave fundamental data for preparation of hazard map published by local government.

Volcanoes: Asama, Aogashima, Aso, Hokkaido-Komagatake, Iwate, Izu-Oshima, Kirishima, Kusatsu-Shirane, Miyakejima, Nasu, Sakurajima, Unzen, Usu

Geological Researches on Active Volcanoes: Satsuma-iojima

"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.
