This work assesses the feasibility of the direct use of surface-wave dispersion curves from seismic ambient noise to gain insight into the crustal structure of Bransfield Strait and detect seasonal seismic velocity changes. We cross-correlated four years of vertical component ambient noise data recorded by a seismic array in West Antarctica. To estimate fundamental mode Rayleigh wave Green’s functions, the correlations are computed in 4-hr segments, stacked over 1-year time windows and moving…

Body wave observations from cross‐correlations of ambient seismic noise: A case study from the Karoo, RSA

In the past decade the analysis of seismic noise has become an efficient tool to recover the Green's function between pairs of receivers by cross‐correlation of seismic traces. Most studies focus on

Ambient noise Rayleigh wave tomography across Europe

SUMMARY We extend ambient noise surface wave tomography both in bandwidth (10‐50 s period) and in geographical extent (across much of Europe) compared with previous applications. 12 months of ambient

Assessment of resolution and accuracy of the Moving Window Cross Spectral technique for monitoring crustal temporal variations using ambient seismic noise

SUMMARY Temporal variations in the elastic behaviour of the Earth’s crust can be monitored through the analysis of the Earth’s seismic response and its evolution with time. This kind of analysis

Seismic interferometry of railroad induced ground motions: body and surface wave imaging

S U M M A R Y Seismic interferometry applied to 120 hr of railroad traffic recorded by an array of vertical component seismographs along a railway within the Rio Grande rift has recovered surface and

Detecting seasonal variations in seismic velocities within Los Angeles basin from correlations of ambient seismic noise

SUMMARY We analyse 3 yr of continuous seismic records from broad-band stations of the Caltech Regional Seismic Network (CI) in vicinity of the Los Angeles basin. Using correlations of ambient seismic

Emergence of broadband Rayleigh waves from correlations of the ambient seismic noise

We demonstrate that the coherent information about the Earth structure can be extracted from the ambient seismic noise. We compute cross‐correlations of vertical component records of several days of

Effects of seasonal changes in ambient noise sources on monitoring temporal variations in crustal properties

Continuous data recorded at 39 broadband stations near the Longmen Shan Fault operated by the China Earthquake Administration from 1 January 2008 to 30 September 2010 are used to study temporal
