We calculate cross correlation functions (CCFs) of ambient noises recorded by four seismic stations on the active volcano from 1 January 2012 to 31 December 2015 at 0.5–1 Hz, 1–2 Hz, and 2–4 Hz. Applying moving time windows to calculate cross spectrum between daily CCFs and reference CCF, which is the average for the all observation period, we compute daily velocity changes. The obtained velocity changes vary from −1% to 3% with a dominant period of about 1 year. We calculate areal strains by using Global Navigation Satellite Systems data at the volcano. It is evident that the velocity changes are well correlated with the areal strain changes whose linear trend is removed. The stress sensitivity of velocity changes, which are obtained from the observed velocity changes and areal strains, is lower at 0.5–1 Hz than that at higher frequencies: (7.1 ± 1.3) × 10<jats:sup>−8</jats:sup> Pa<jats:sup>−1</jats:sup> at 0.5–1 Hz, (1.4 ± 0.1) × 10<jats:sup>−7</jats:sup> Pa<jats:sup>−1</jats:sup> at 1–2 Hz, and (1.3 ± 0.1) × 10<jats:sup>−7</jats:sup> Pa<jats:sup>−1</jats:sup> at 2–4 Hz. Modeling the velocity changes of Rayleigh wave propagating in layered structures, we find that the observed velocity changes are concentrated in the upper 1 km of the structure. Since similar frequency dependency is recognized among the stress sensitivity of velocity changes reported in previous studies, we conclude that the velocity changes are localized in the shallow depth because of the increase of confining pressure.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004229808479362","@type":"Researcher","foaf:name":[{"@value":"Tomoya Takano"}],"jpcoar:affiliationName":[{"@value":"Department of Geophysics, Graduate School of Science Tohoku University  Sendai Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004229808479360","@type":"Researcher","foaf:name":[{"@value":"Takeshi Nishimura"}],"jpcoar:affiliationName":[{"@value":"Department of Geophysics, Graduate School of Science Tohoku University  Sendai Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004229808479241","@type":"Researcher","foaf:name":[{"@value":"Hisashi Nakahara"}],"jpcoar:affiliationName":[{"@value":"Department of Geophysics, Graduate School of Science Tohoku University  Sendai Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"21699313"},{"@type":"EISSN","@value":"21699356"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2017-08","prism:volume":"122","prism:number":"8","prism:startingPage":"6721","prism:endingPage":"6736"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2F2017JB014340"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1002/2017JB014340"}],"createdAt":"2017-08-17","modifiedAt":"2023-09-10","project":[{"@id":"https://cir.nii.ac.jp/crid/1040282256937413504","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"17J02025"},{"@type":"JGN","@value":"JP17J02025"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17J02025/"}],"notation":[{"@language":"ja","@value":"地震波干渉法解析に基く、地震波速度変化の応力感度特性の解明"}]}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050282810721880064","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["references"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Monitoring seismic velocity change caused by the 2011 Tohoku-oki earthquake using ambient noise records"},{"@value":"Monitoring seismic velocity change caused by the 2011 Tohoku‐oki earthquake using ambient noise records"}]},{"@id":"https://cir.nii.ac.jp/crid/1360002216708238976","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Temporal change of phase velocity beneath Mt.
