Then we calculate the average amplitude attenuation due to scattering in an infinite random slab. We slice the random slab into layers of thickness a correlation length and use the Born approximation for each slice to calculate the scattered field. To include the effect of multiple scattering, we take the back‐halfspace integration of the scattered energy as the energy loss and do energy correction for each successive slice. Taking scalar wave approximation for seismic waves, we get a formula for average amplitude attenuation essentially valid for high frequency range (ka»1). The attenuation depends strongly on the form of correlation function of the random inhomogeneities. We derive the formulas for Gaussian, exponential and Von Kárman correlation functions. The frequency dependence of attenuation by our formulation agrees well with experiments.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380016868817975040","@type":"Researcher","foaf:name":[{"@value":"Wu Ru‐Shan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"1982-01","prism:volume":"9","prism:number":"1","prism:startingPage":"9","prism:endingPage":"12"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2FGL009i001p00009"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/GL009i001p00009"}],"createdAt":"2008-02-06","modifiedAt":"2023-09-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050845760708107136","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Numerical analysis of the relationship between time-variant coda-Q and the variation in crustal stress"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567184391578496","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Detailed study of seismic wave attenuation from four oilfields in Abu Dhabi, United Arab Emirates"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001205636512896","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"減衰定数の下限値を考慮したスペクトル比の逆解析による同定手法の提案 : 岩盤における鉛直アレイ記録への適用と減衰特性の評価"},{"@language":"en","@value":"IDENTIFICATION OF DAMPING FACTOR CONSIDERING ITS LOWER LIMIT BY SPECTRAL RATIO INVERSION : Application to borehole array records at hard rock sites and evaluation of attenuation characteristics"},{"@language":"ja-Kana","@value":"ゲンスイ テイスウ ノ カゲンチ オ コウリョ シタ スペクトルヒ ノ ギャクカイセキ ニ ヨル ドウテイ シュホウ ノ テイアン ガンバン ニ オケル エンチョク アレイ キロク エ ノ テキヨウ ト ゲンスイ トクセイ ノ ヒョウカ"},{"@value":"Identification of damping factor considering its lower limit by spectral ratio inversion—application to borehole array records at hard rock sites and evaluation of attenuation characteristics"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206510238336","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Spatial variation of coda wave amplitude in media with a localized heterogeneous region"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679279758464","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Scattering Theory for Short-Period Seismic Waves : Velocity Shift and Envelopes in Random Media"},{"@language":"ja","@value":"短周期地震波の散乱理論"},{"@value":"短周期地震波の散乱理論--ランダム媒質における走時と波形エンベロープ"},{"@language":"ja-Kana","@value":"タンシュウキ ジシンハ ノ サンラン リロン ランダム バイシツ ニ オケル ソウジ ト ハケイ エンベロープ"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892094267776","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Numerical simulations to explain the coseismic electromagnetic signals : a case study for a M5.4 aftershock of the 2016 Kumamoto earthquake"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/gl009i001p00009"},{"@type":"CROSSREF","@value":"10.1093/gji/ggt243_references_DOI_6gfdMCTWPX9M3uR1C3n1TkJX0Nj"},{"@type":"CROSSREF","@value":"10.4294/zisin.61.93_references_DOI_6gfdMCTWPX9M3uR1C3n1TkJX0Nj"},{"@type":"CROSSREF","@value":"10.3130/aijs.71.55_2_references_DOI_6gfdMCTWPX9M3uR1C3n1TkJX0Nj"},{"@type":"CROSSREF","@value":"10.1088/1742-2140/aa9a08_references_DOI_6gfdMCTWPX9M3uR1C3n1TkJX0Nj"},{"@type":"CROSSREF","@value":"10.1186/s40623-019-1122-7_references_DOI_6gfdMCTWPX9M3uR1C3n1TkJX0Nj"},{"@type":"CROSSREF","@value":"10.1186/bf03352117_references_DOI_6gfdMCTWPX9M3uR1C3n1TkJX0Nj"}]}
