The delta S-34 values of water-soluble sulphate leached from volcanic ash effused during intermittent eruptions from July to September 2005 range from +5 to +11 parts per thousand with a fluctuation of ca 3 parts per thousand within a single eruption. The delta S-34 value of sulphuric acid mist collected with \u0027Cu-metal trap\u0027 placed on the flank of the volcano from December 2000 to January 2001 is +6.2 parts per thousand. These sulphur isotopic compositions of sulphate, which were isotopically equilibrated in the subvolcanic hydrothermal system, indicate that the temperature of the hydrothermal system beneath the caldera increased after the period of intermittent phreatic and phreatomagmatic eruptions. Then, the delta S-34 value of sulphuric acid trapped from January to March 2001 was +9.0 parts per thousand and the delta S-34 value of water-soluble sulphate on volcanic ash emitted with minor eruption in May 2001 was +11.0 parts per thousand, suggesting a decrease in temperature of the subvolcanic hydrothermal system.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "BLACKWELL PUBLISHING", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1111/j.1440-1738.2007.00549.x"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1038-4871", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Akira Imai", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Nobuo Geshi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Taketo Shimano", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Setsuya Nakada", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Implication of the temporal sulphur isotopic variation during the 2000 eruption of Miyakejima Volcano, Japan", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Implication of the temporal sulphur isotopic variation during the 2000 eruption of Miyakejima Volcano, Japan", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4777", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4777", "relation": {}, "relation_version_is_last": true, "title": ["Implication of the temporal sulphur isotopic variation during the 2000 eruption of Miyakejima Volcano, Japan"], "weko_shared_id": -1}
