OCEQ b-values in the youngest (\u003c10 Ma) oceanic lithosphere are around 1.0, while those in middle to old (\u003e20 Ma) oceanic lithosphere exceed 1.5, which is significantly higher than the average worldwide earthquake b-value (around 1.0). On the other hand, the b-value of intraplate earthquakes in the Ninety East-Sumatra orogen, where oceanic lithosphere has an anomalously higher strain rate compared with normal oceanic lithosphere, is 0.93, which is significantly lower than the OCEQ b-value (about 1.9) with the same age (50\u2013110 Ma). Thus, the variation in b-values relates to the strain rate of the oceanic lithosphere and is not caused by a difference in thermal structure. We revealed a negative strain rate dependency of the b-value at extremely low strain rates (\u003c2 \u00d7 10\u221210/year), which can clearly explain the above b-values. We propose that the OCEQ b-value depends strongly on strain rate (either directly or indirectly) at extremely low strain rates. The high OCEQ b-values (\u003e1.5) in oceanic lithosphere \u003e20 Ma old imply that future improvement in seismic observation will capture many smaller magnitude OCEQs, which will provide valuable information on the evolution of the oceanic lithosphere and the driving mechanism of plate tectonics.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://doi.org/10.1002/2016JB013221"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/25180"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Wiley"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2016 American Geophysical Union"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2169-9356", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Sasajima, Ryohei"}], "nameIdentifiers": [{"nameIdentifier": "67952", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ito, Takeo"}], "nameIdentifiers": [{"nameIdentifier": "67953", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-12-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Sasajima_et_al-2016-Journal_of_Geophysical_Research_Solid_Earth.pdf", "filesize": [{"value": "1.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1700000.0, "url": {"label": "Sasajima_et_al-2016-Journal_of_Geophysical_Research_Solid_Earth.pdf \u30d5\u30a1\u30a4\u30eb\u516c\u958b\uff1a2017/12/29", "url": "https://nagoya.repo.nii.ac.jp/record/22996/files/Sasajima_et_al-2016-Journal_of_Geophysical_Research_Solid_Earth.pdf"}, "version_id": "df7aa0a5-7c27-44b6-9979-c9e64c3a86dd"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Strain rate dependency of oceanic intraplate earthquake b-values at extremely low strain rates", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Strain rate dependency of oceanic intraplate earthquake b-values at extremely low strain rates"}]}, "item_type_id": "10", "owner": "1", "path": ["488/489/490"], "permalink_uri": "http://hdl.handle.net/2237/25180", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2016-12-12"}, "publish_date": "2016-12-12", "publish_status": "0", "recid": "22996", "relation": {}, "relation_version_is_last": true, "title": ["Strain rate dependency of oceanic intraplate earthquake b-values at extremely low strain rates"], "weko_shared_id": null}
