The List of volcanoes and Their Activities Records in the Adjacent Seas of Japan 2nd Revised Edition

Abstract

The Hydrographic Department of Japan actively participates in The Volcanic Eruption Prediction Plan since the Plan started in 1973. Observation of volcanic activities in the adjacent seas of Japan is very important, not only to protect safety navigation, fishery and other activities in the sea area against a disaster, but also to manage the sea area itself effectively. This list is a 2nd revised edition of “The List of Volcanoes and Their Activities Records in the Adjacent Seas of Japan" prepared by lwabuchi, Kato and Shibata (1994). There is no intensive volcanic eruption occurred in the sea area during the past five years, but a lot of fundamental data on geology and geophysics were collected from the surveys on Sumisu Sima, Tori Sima, Sohu Gan, Hatizyo Sima in the Nanpo Syoto arc and Others.
