Interferometric Multichannel Analysis of Surface Waves (IMASW)

Bulletin of the Seismological Society of America, 2011
Abstract Refraction microtremor (ReMi) and multichannel analysis of surface waves (MASW) are effective approaches to estimate shallow shear-wave velocity ( V S ) structure often needed to estimate ground motions using recent ground motion prediction relations.

Multichannel analysis of surface wave method with the autojuggie

Soil Dynamics and Earthquake Engineering, 2003
Abstract The shear (S)-wave velocity of near-surface materials and its effect on seismic-wave propagation are of fundamental interest in many engineering, environmental, and groundwater studies. The multichannel analysis of surface wave (MASW) method provides a robust, efficient, and accurate tool to observe near-surface S-wave velocity.

Multichannel analysis of surface waves to map bedrock

The Leading Edge, 1999
In many geologic settings, topographic variations and discontinuities in the surface of bedrock can influence the transport and eventual fate of contaminants introduced at or near the ground surface. Determining the nature and location of anomalous bedrock can be an essential component of hydrologic characterization.

Roadside Passive Multichannel Analysis of Surface Waves (MASW)

Journal of Environmental and Engineering Geophysics, 2008
Abstract A 2-D receiver array, such as a cross or circular type, should be used in a passive surface wave survey to provide the most accurate results. It is often not possible to secure such a spacious area, however, especially if the survey has to take place in an urban area.

Multichannel analysis of passive surface waves based on crosscorrelations

Geophysics, 2016
ABSTRACT 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.

Assessing combined analysis of electrical resistivity tomography and multichannel analysis of surface waves for ground improvement assessment near by-pass road, Silchar, Assam

Exploration Geophysics, 2023
Soft clayey soils are generally improved by the consolidation process. The different improvement techniques which are in vogue include the use of stone columns, sand drains with and without preload and prefabricated vertical drains. Upon improvement, the

Offset And Resolution Of Dispersion Curve In Multichannel Analysis Of Surface Waves (Masw)

14th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2001
Influence of offset-related parameters on the resolution of dispersion curve in multichannel analysis of surface waves (MASW) surveys is described from the theoretical perspective of the dispersion curve imaging method used during a normal implementation of MASW.

Multichannel Analysis of Passive Surface Waves – Modeling and Processing Schemes

Site Characterization and Modeling, 2005
Characteristics of phase velocity and incoming angle (azimuth) of passive surface waves as they are observed with a multichannel processing scheme are studied through both synthetic modeling and field experiments. They are analyzed specifically in association with the case of multiple sources and multiple modes of dispersion.
