This increase suggests that the static stress change due to a large earthquake causes a change in the crustal condition of dynamics. In order to reveal the changes quantitatively, we investigate the temporal variation in coda Q-1 and b value in the Tamba region. We analyze the waveform data of many shallow microearthquakes (M 1.5-3.0) in the region recorded in a period from 1987 to 1996. Coda Q-1 is estimated in 10 frequency bands in a range of 1.5-24 Hz based on the single isotropic scattering model. At frequencies between 1.5 and 4.0 Hz the temporal variation in coda Q-1 shows significant correlation with the occurrence of the Hyogo-ken Nanbu earthquake; coda Q-1 increases after the event. A variation in b value whose sign is opposite to that of coda Q-1 is recognized. The fracture dimensions of microearthquakes that contribute to the variation in b value are estimated to be 400 m. This scale length is consistent with the characteristic scale length of scatter, 300-600 m, which contributes effectively to a temporal variation in coda Q-1. The crustal activity in the Tamba region is possibly controlled by the heterogeneity with dominant scale of 102 m. The stress sensitivity of the coda Q-1 change is estimated to be 10 (MPa)-1. This value is an order of magnitude larger than the stress sensitivity of seismic velocity reported before.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00010414","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Geophysical Union (AGU)"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1029/1999jb900432","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA10819743","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0148-0227","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hiramatsu, Yoshihiro"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Hayashi, Nobuhiko"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Furumoto, Muneyoshi"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Katao, Hiroshi"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"SC-PR-HIRAMATSU-Y-6141.pdf","filesize":[{"value":"593.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-HIRAMATSU-Y-6141.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/10427/files/SC-PR-HIRAMATSU-Y-6141.pdf"},"version_id":"afd5ffaa-0153-4df8-bc8b-1d10902a1f22"}]},"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":"Temporal changes in coda Q-1 and b value due to the static stress change associated with the 1995 Hyogo-ken Nanbu earthquake","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temporal changes in coda Q-1 and b value due to the static stress change associated with the 1995 Hyogo-ken Nanbu earthquake"}]},"item_type_id":"4","owner":"3","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"10427","relation_version_is_last":true,"title":["Temporal changes in coda Q-1 and b value due to the static stress change associated with the 1995 Hyogo-ken Nanbu earthquake"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:58:06.685080+00:00"}
