{"cited_by_count":771232,"description":"This cluster of papers focuses on the high-resolution tomographic imaging of the Earth's subsurface using ambient seismic noise, particularly surface wave tomography and the extraction of Green's functions. It encompasses techniques such as seismic interferometry, cross-correlation of noise data, and distributed acoustic sensing for monitoring seismic events and subsurface structures. The research also explores applications in characterizing near-surface geological features and monitoring changes in seismic velocity over time.","display_name":"Seismic Waves and Analysis","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11757","wikipedia":"https://en.wikipedia.org/wiki/Ambient_noise_seismology"},"field_id":"19","id":"T11757","keywords":[{"display_name":"synthetic seismograms","id":"synthetic-seismograms","score":0.6731,"url":"https://openalex.org/keywords/synthetic-seismograms"},{"display_name":"earthquake ground motion simulation","id":"ground-motion-simulation","score":0.7735,"url":"https://openalex.org/keywords/ground-motion-simulation"},{"display_name":"crustal structure","id":"crustal-structure","score":0.2042,"url":"https://openalex.org/keywords/crustal-structure"},{"display_name":"seismic wave propagation","id":"seismic-wave-propagation","score":0.2746,"url":"https://openalex.org/keywords/seismic-wave-propagation"},{"display_name":"surface-wave radiation patterns","id":"surface-wave-radiation-patterns","score":0.9638,"url":"https://openalex.org/keywords/surface-wave-radiation-patterns"},{"display_name":"Rayleigh waves","id":"rayleigh-waves","score":0.3986,"url":"https://openalex.org/keywords/rayleigh-waves"},{"display_name":"horizontal-to-vertical spectral ratio","id":"horizontal-to-vertical-spectral-ratio","score":0.7186,"url":"https://openalex.org/keywords/horizontal-to-vertical-spectral-ratio"},{"display_name":"microtremor","id":"microtremor","score":0.6638,"url":"https://openalex.org/keywords/microtremor"},{"display_name":"Love waves","id":"love-waves","score":0.5951,"url":"https://openalex.org/keywords/love-waves"},{"display_name":"seismic attenuation","id":"seismic-attenuation","score":0.223,"url":"https://openalex.org/keywords/seismic-attenuation"},{"display_name":"seismic velocity structure","id":"seismic-velocity-structure","score":0.288,"url":"https://openalex.org/keywords/seismic-velocity-structure"},{"display_name":"USArray","id":"usarray","score":0.7634,"url":"https://openalex.org/keywords/usarray"},{"display_name":"ambient seismic noise","id":"ambient-seismic-noise","score":0.8856,"url":"https://openalex.org/keywords/ambient-seismic-noise"},{"display_name":"distributed acoustic sensing","id":"distributed-acoustic-sensing","score":0.2925,"url":"https://openalex.org/keywords/distributed-acoustic-sensing"},{"display_name":"ground motion visualization","id":"ground-motion-visualization","score":0.7306,"url":"https://openalex.org/keywords/ground-motion-visualization"},{"display_name":"S-wave velocity structure","id":"shear-wave-velocity-structure","score":0.7425,"url":"https://openalex.org/keywords/shear-wave-velocity-structure"},{"display_name":"receiver functions","id":"receiver-functions","score":0.4288,"url":"https://openalex.org/keywords/receiver-functions"},{"display_name":"site amplification","id":"ground-motion-amplification","score":0.2415,"url":"https://openalex.org/keywords/ground-motion-amplification"},{"display_name":"infrasound","id":"infrasound","score":0.2483,"url":"https://openalex.org/keywords/infrasound"},{"display_name":"ambient noise tomography","id":"ambient-noise-tomography","score":0.9172,"url":"https://openalex.org/keywords/ambient-noise-tomography"},{"display_name":"seismic noise","id":"seismic-noise","score":0.4872,"url":"https://openalex.org/keywords/seismic-noise"},{"display_name":"surface wave dispersion","id":"surface-wave-dispersion","score":0.7091,"url":"https://openalex.org/keywords/surface-wave-dispersion"},{"display_name":"Rayleigh wave dispersion","id":"rayleigh-wave-dispersion","score":0.8305,"url":"https://openalex.org/keywords/rayleigh-wave-dispersion"},{"display_name":"ocean bottom seismometers","id":"ocean-bottom-seismometers","score":0.2502,"url":"https://openalex.org/keywords/ocean-bottom-seismometers"},{"display_name":"seismic interferometry","id":"seismic-interferometry","score":0.6896,"url":"https://openalex.org/keywords/seismic-interferometry"}],"legacy_keywords":["Seismic Noise","Tomography","Surface Wave","Ambient Seismic","Green's Function","Rayleigh Wave","Interferometry","Microseisms","Distributed Acoustic Sensing","Inversion"],"openalex_id":"https://openalex.org/T11757","source_created_date":"2024-01-23T15:27:11","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1908","url":"/topics/T11757","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11757","works_count":89441,"label":"Seismic Waves and Analysis","provider":"openalex","revision":"7f7d9aa4b6569597","taxonomy_revision":"f050b5d4780b1289","title":"Seismic Waves and Analysis","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36183057426189371","address_version":"morton4x16-v1","coordinates":[3,19,1908,11757],"answer_status":"Directory metadata;
