This study examined a landslide in central Japan that produced clearly detectable seismic signals at multiple seismic stations in a permanent network. Wave packets propagated with a group velocity of 3  km/s from the landslide area. Using a source location determination method with amplitude information from the high-frequency component, the source location of the wave packets was shown to be in the vicinity of the landslide with an error of 5 km. Moreover, seismograms specific to this landslide also contained a distinct impulsive phase with a source located in the vicinity of the landslide. The study demonstrated that seismic waves with a high-frequency component from landslides can be used to estimate their mechanisms as well as their locations when they are recognized by a routine seismic network.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825896388930816","@type":"Researcher","foaf:name":[{"@value":"Issei Doi"}],"jpcoar:affiliationName":[{"@value":"Disaster Prevention Research Institute, Kyoto University, Kyoto, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825896388930817","@type":"Researcher","foaf:name":[{"@value":"Takuto Maeda"}],"jpcoar:affiliationName":[{"@value":"Graduate School of Science and Technology, Hirosaki University, Hirosaki, Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"08950695"},{"@type":"EISSN","@value":"19382057"}],"prism:publicationName":[{"@value":"Seismological Research Letters"}],"dc:publisher":[{"@value":"Seismological Society of America (SSA)"}],"prism:publicationDate":"2020-07-22","prism:volume":"91","prism:number":"5","prism:startingPage":"2719","prism:endingPage":"2729"},"reviewed":"false","url":[{"@id":"https://pubs.geoscienceworld.org/ssa/srl/article-pdf/91/5/2719/5142791/srl-2020032.1.pdf"}],"createdAt":"2020-07-22","modifiedAt":"2020-09-02","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050006662412208000","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Identifying landslides from continuous seismic surface waves: a case study of multiple small-scale landslides triggered by Typhoon Talas, 2011"}]},{"@id":"https://cir.nii.ac.jp/crid/1390011650976080000","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Seismic waves excited by debris flows at Meakandake volcano on 20 May 2008"},{"@language":"ja","@value":"2008年5月20日に雌阿寒岳で発生した土石流に伴う地震波の記録"}]},{"@id":"https://cir.nii.ac.jp/crid/1390583238591324928","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"A shallow landslide detected by a close-range seismometer"},{"@language":"ja","@value":"極至近距離に設置された地震計によって捉えられた表層崩壊"}]},{"@id":"https://cir.nii.ac.jp/crid/1390850857224033280","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Landslide Location and Generation Characteristics Estimated Using Seismogram records"},{"@language":"ja","@value":"地震波形記録による斜面崩壊の発生場所と発生形態の推定"},{"@value":"地震波形記録による斜面崩壊の発生場所と発生形態の推定 : 2017年九州北部豪雨災害・日田市小野地区の斜面崩壊を例として"},{"@language":"ja-Kana","@value":"ジシン ハケイ キロク ニ ヨル シャメン ホウカイ ノ ハッセイ バショ ト ハッセイ ケイタイ ノ スイテイ : 2017ネン キュウシュウ ホクブ ゴウウ サイガイ ・ ヒタシ オノ チク ノ シャメン ホウカイ オ レイ ト シテ"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842055369344","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Estimation of relative source locations from seismic amplitude : application to earthquakes and tremors at Meakandake volcano, eastern Hokkaido, Japan"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1785/0220200032"},{"@type":"OPENAIRE","@value":"doi_dedup___::8aee69286c2b1d954fe4bf431dbbf697"},{"@type":"CROSSREF","@value":"10.1186/s40623-021-01366-8_references_DOI_Nw6rsD5yee19lHjlzAqRnd17ow9"},{"@type":"CROSSREF","@value":"10.5110/jjseg.61.245_references_DOI_Nw6rsD5yee19lHjlzAqRnd17ow9"},{"@type":"CROSSREF","@value":"10.3313/jls.59.146_references_DOI_Nw6rsD5yee19lHjlzAqRnd17ow9"},{"@type":"CROSSREF","@value":"10.3313/jls.61.193_references_DOI_Nw6rsD5yee19lHjlzAqRnd17ow9"},{"@type":"CROSSREF","@value":"10.1093/gji/ggab129_references_DOI_Nw6rsD5yee19lHjlzAqRnd17ow9"}]}
