It is found that the subducting Philippine Sea and Pacific plates are characterized by high-Q zones. A high-Q zone also exists between the Philippine Sea plate and the Pacific plate, to the east of the volcanic front. On the other hand, a low-Q zone in the uppermost mantle extends westward horizontally from the volcanic front under the Philippine Sea plate, and appears to exist over the wedge mantle beneath the western Tokai district. A very low Q value obtained here is roughly equal to the average Q value in the low-velocity layer derived from surface wave and free oscillation data. A low-Q region that suggests a magma chamber under active volcanoes is not detected in the crust.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "ELSEVIER SCIENCE BV", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1016/0040-1951(91)90145-I"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0040-1951", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "S SEKIGUCHI", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "3-DIMENSIONAL Q STRUCTURE BENEATH THE KANTO-TOKAI DISTRICT, JAPAN", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "3-DIMENSIONAL Q STRUCTURE BENEATH THE KANTO-TOKAI DISTRICT, JAPAN", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4217", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4217", "relation": {}, "relation_version_is_last": true, "title": ["3-DIMENSIONAL Q STRUCTURE BENEATH THE KANTO-TOKAI DISTRICT, JAPAN"], "weko_shared_id": -1}
