Surface-consistent amplitude corrections for single or multicomponent sources and receivers using reciprocity and waveform inversion [PDF]

, 2006
In land seismics, near-surface conditions often vary within surveys, resulting in differences in source strength and signature. Furthermore, discrepancies between closely spaced recordings are also commonly observed.

Application of Multichannel Analysis of Surface Waves to S-Phase Wave Anisotropy Estimation [PDF]

Acta Geophysica, 2016
The Multichannel Analysis of Surface Waves (MASW) is an increasingly used technique for recognition of a shallow geological structure and estimation of geotechnical parameters, e.g., S-wave velocity, layer density, layer thickness, shear modulus, estimated P-wave velocity, and estimated Poisson ratio.

Results of field testing of municipal solid waste by combination of CPTU and MASW

Data in Brief, 2018
The cone penetration testing of MSW by piezocone (CPTU) in combination with the multichannel analysis of surface waves (MASW) provide extensive data about estimated values of physico-mechanical properties of wastes, which are usually unavailable in ...
