Along-arc variation in thickness of the arc crust has been observed by previous active seismic surveys beneath the Izu-Bonin arc. We have imaged three-dimensional (3-D) seismic velocity structures in the northern Izu-Bonin arc using arrival time data of the earthquakes during 80 days of observations by ocean bottom seismographs and three permanent island seismic stations. Our 3-D velocity model indicates heterogeneous structure in the mantle wedge along the arc. Low-velocity anomalies related to upwelling flow in the mantle wedge are not uniform beneath the volcanic front. Low-velocity anomalies extending down to the subducting slab beneath the volcanic front coincide with thicker parts of the arc crust north of Aoga-shima and south of Sumisu-jima. This coincidence suggests that heterogeneous mantle upwelling flow fundamentally controls the growth of the arc crust. Along topographic highs in the forearc, low-velocity anomalies in the crust and uppermost mantle coincide with positive magnetic anomalies suggesting the presence of a remnant arc, providing further evidence of this view of arc crust formation.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "AMER GEOPHYSICAL UNION", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1029/2010GC003146"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1525-2027", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Obana Koichiro", "creatorNameLang": "ja"}, {"creatorName": "Obana Koichiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kamiya Shinichiro", "creatorNameLang": "ja"}, {"creatorName": "Kamiya Shinichiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kodaira Shuichi", "creatorNameLang": "ja"}, {"creatorName": "Kodaira Shuichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Suetsugu Daisuke", "creatorNameLang": "ja"}, {"creatorName": "Suetsugu Daisuke", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takahashi Narumi", "creatorNameLang": "ja"}, {"creatorName": "Takahashi Narumi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takahashi Tsutomu", "creatorNameLang": "ja"}, {"creatorName": "Takahashi Tsutomu", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tamura Yoshihiko", "creatorNameLang": "ja"}, {"creatorName": "Tamura Yoshihiko", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Along-arc variation in seismic velocity structure related to variable growth of arc crust in northern Izu-Bonin intraoceanic arc", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Along-arc variation in seismic velocity structure related to variable growth of arc crust in northern Izu-Bonin intraoceanic arc", "subitem_title_language": "ja"}, {"subitem_title": "Along-arc variation in seismic velocity structure related to variable growth of arc crust in northern Izu-Bonin intraoceanic arc", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4529", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4529", "relation": {}, "relation_version_is_last": true, "title": ["Along-arc variation in seismic velocity structure related to variable growth of arc crust in northern Izu-Bonin intraoceanic arc"], "weko_shared_id": -1}
