TL;DR: The 2020 seismic noise quiet period is the longest and most prominent global anthropogenic seismic noise reduction on record and suggests that seismology provides an absolute, real-time estimate of human activities.
Journal ArticleDOI
Cancellation of spurious arrivals in Green's function extraction and the generalized optical theorem
TL;DR: It is shown that for an arbitrary small scatterer, the cross terms of scattered waves give an unphysical wave with an arrival time that is independent of the source position, and an alternative derivation of the generalized optical theorem is constituted.
Journal ArticleDOI
Extension of the Spatial Autocorrelation (SPAC) Method to Mixed-Component Correlations of Surface Waves
TL;DR: In this article, the authors present a theoretical analysis of the spatial autocorrelation (SPAC) method for multicomponent recordings of surface waves to determine the complete 3 × 3 matrix of correlations between all pairs of three-component motions.
Journal ArticleDOI
Physical modeling and analysis of P-wave attenuation anisotropy in transversely isotropic media
TL;DR: In this article, the spectral-ratio method was used to estimate the group effective attenuation coefficient of P-waves transmitted through the sample for a wide range of propagation angles from 0° to 90° with the symmetry axis.
Journal ArticleDOI
The virtual refraction: Useful spurious energy in seismic interferometry
TL;DR: In this paper, the authors used a spurious wave associated with the crosscorrelation of refracted energy at both receivers to infer estimates of subsurface parameters and found that the slope of the virtual refraction defines the velocity of the faster medium.
