In the context of the resolved structure, we discuss the relationship between the fault rupture of the 2016 Kumamoto earthquake and Aso volcano. Low-density bodies were resolved beneath central Aso volcano using a three-dimensional inversion with an assumed density contrast of ±0.3 g/cm3.  The resultant location of the southern low-density body is onsistent with a magma reservoir reported in previous studies. No Kumamoto aftershocks occur in the southern low-density body; this aseismic anomaly may indicate a ductile feature due to high temperatures and/or the presence of partial melt. Comparisons of the location of the southern low-density body with rupture models of the mainshock, obtained from teleseismic waveform and InSAR data, suggest that the rupture terminus overlaps the southern low-density body. The ductile features of a magma reservoir could have terminated rupture propagation. On the other hand, a northern low-density body is resolved in the Asodani area, where evidence of current volcanic activity is scarce and aftershock activity is high. The northern low-density body might, therefore, be derived from a thick caldera fill in the Asodani area, or correspond to mush magma or a high-crystallinity magma reservoir that could be the remnant of an ancient intrusion.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":" Springer  "}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1186/s40623-016-0582-2","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© The Author(s) 2016."},{"subitem_rights":"This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made."}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-5981","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Miyakawa, Ayumu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sumita, Tatsuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okubo, Yasukuni"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okuwaki, Ryo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Otsubo, Makoto"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uesawa, Shimpei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yagi, Yuji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-31"}],"displaytype":"detail","filename":"EPS_68-208.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"EPS_68-208","url":"https://tsukuba.repo.nii.ac.jp/record/40182/files/EPS_68-208.pdf"},"version_id":"5cf46340-5b0b-4925-9f4e-78d35a5ef4a6"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Volcanic magma reservoir imaged as a low-density body beneath Aso volcano that terminated the 2016 Kumamoto earthquake rupture","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Volcanic magma reservoir imaged as a low-density body beneath Aso volcano that terminated the 2016 Kumamoto earthquake rupture"}]},"item_type_id":"5","owner":"1","path":["2943","5390"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-01-31"},"publish_date":"2017-01-31","publish_status":"0","recid":"40182","relation_version_is_last":true,"title":["Volcanic magma reservoir imaged as a low-density body beneath Aso volcano that terminated the 2016 Kumamoto earthquake rupture"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:10:29.368740+00:00"}
