Multichannel analysis of surface waves

GEOPHYSICS, 1999
The frequency‐dependent properties of Rayleigh‐type surface waves can be utilized for imaging and characterizing the shallow subsurface. Most surface‐wave analysis relies on the accurate calculation of phase velocities for the horizontally traveling fundamental‐mode Rayleigh wave acquired by stepping out a pair of receivers at intervals based on ...

Horizontal resolution of multichannel analysis of surface waves

GEOPHYSICS, 2017
The multichannel analysis of surface wave (MASW) method has been effectively and widely used to determine near-surface shear-wave velocity. Horizontal resolution of the MASW method represents the minimum horizontal length of recognizable geologic anomalous bodies on a pseudo-2D S-wave velocity [Formula: see text] section.

Multichannel analysis of passive surface waves based on crosscorrelations

GEOPHYSICS, 2016
Passive seismic methods in highly populated urban areas have gained much attention from geophysics and civil engineering communities because traditional seismic surveys, especially in complex urbanized environments, might be improperly applied. In passive seismic methods, directional noise sources will inevitably bring azimuthal effects and spatial ...

Passive multichannel analysis of surface waves using 1D and 2D receiver arrays

GEOPHYSICS, 2021
We use the seismic multichannel analysis of surface waves (MASW) method, which originally used active sources (i.e., controlled by users), to present a new alternative technique for surface-wave analysis of passive data (i.e., seismic sources not controlled by users).
