LP events might be of particular interest to understanding eruptive processes as their source mechanism is assumed to directly involve fluid transport. However, it is usually difficult or impossible to locate their source using traditional arrival time methods because of emergent wave arrivals. At Kilauea, similar LP waveform signatures suggest the existence of LP multiplets. The waveform similarity suggests spatially close sources, while catalog solutions using arrival time estimates are widely scattered beneath Kilauea's summit caldera. In order to improve estimates of absolute LP location, we use the distribution of seismic amplitudes corrected for station site effects. The decay of the amplitude as a function of hypocentral distance is used for inferring LP location. In a second stage, we use the similarity of the events to calculate their relative positions. The analysis of the entire LP seismicity recorded between January 1997 and December 1999 suggests that a very large part of the LP event population, both deep and shallow, is generated by a small number of compact sources. Deep events are systematically composed of a weak high‐frequency onset followed by a low‐frequency wave train. Aligning the low‐frequency wave trains does not lead to aligning the onsets indicating the two parts of the signal are dissociated. This observation favors an interpretation in terms of triggering and resonance of a magmatic conduit. Instead of defining fault planes, the precise relocation of similar LP events, based on the alignment of the high‐energy low‐frequency wave trains, defines limited size volumes.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381981468618108288","@type":"Researcher","foaf:name":[{"@value":"Jean Battaglia"}],"jpcoar:affiliationName":[{"@value":"Center for the Study of Active Volcanoes  Hilo Hawaii USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1380298341126286465","@type":"Researcher","foaf:name":[{"@value":"Jean‐Luc Got"}],"jpcoar:affiliationName":[{"@value":"Laboratoire de Géophysique Interne et Tectonophysique Université de Savoie  Le Bourget du Lac France"}]},{"@id":"https://cir.nii.ac.jp/crid/1380298341126286464","@type":"Researcher","foaf:name":[{"@value":"Paul Okubo"}],"jpcoar:affiliationName":[{"@value":"U.S. Geological Survey Hawaii Volcano Observatory  Hawaii National Park Hawaii USA"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01480227"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2003-12","prism:volume":"108","prism:number":"B12","prism:startingPage":"2553"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2003JB002517"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2003JB002517"}],"createdAt":"2003-12-04","modifiedAt":"2023-10-14","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050564289223207168","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Estimating plume heights of explosive eruptions using high-frequency seismic amplitudes"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283689328198272","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Theoretical basis of the amplitude source location method for volcano‐seismic signals"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285711273633920","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Repeating Earthquakes"}]},{"@id":"https://cir.nii.ac.jp/crid/1361131418080256384","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Amplitude Source Location Method With Depth‐Dependent Scattering and Attenuation Structures: Application at Nevado del Ruiz Volcano, Colombia"}]},{"@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":"10.1029/2003jb002517"},{"@type":"CROSSREF","@value":"10.1186/s40623-021-01366-8_references_DOI_8QwzDSTFibrBE5idXlvUU4S3M9p"},{"@type":"CROSSREF","@value":"10.1002/2017jb013997_references_DOI_8QwzDSTFibrBE5idXlvUU4S3M9p"},{"@type":"CROSSREF","@value":"10.1146/annurev-earth-053018-060119_references_DOI_8QwzDSTFibrBE5idXlvUU4S3M9p"},{"@type":"CROSSREF","@value":"10.1029/2019jb018156_references_DOI_8QwzDSTFibrBE5idXlvUU4S3M9p"},{"@type":"CROSSREF","@value":"10.1093/gji/ggz374_references_DOI_8QwzDSTFibrBE5idXlvUU4S3M9p"}]}
