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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"4217","relation_version_is_last":true,"title":["3-DIMENSIONAL Q STRUCTURE BENEATH THE KANTO-TOKAI DISTRICT, JAPAN"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-31T01:47:48.304278+00:00"}
