The multichannel analysis of surface wave (MASW) method can be an efficient tool for mapping the near-surface shear-wave velocity (Vs). Data acquisition, dispersion-curve imaging and estimations, inversion, and 2D visualization are distinct MASW components.

APPLICATION OF MULTICHANNEL ANALYSIS OF SURFACE WAVE (MASW) IN GEOTECHNICS
Zbornik radovaMASW (Multichannel Analysis of Surface Waves) is a non-invasive seismic method used for geotechnical site investigations, developed in 1999 in the USA. Its primary purpose is to assess soil stiffness by measuring the shear wave velocity (Vs) beneath the surface, which is crucial for geotechnical analysis.

In the mid-1980s, the surface wave method was initially exhibited as an instrument for the geotechnical engineering field. This non-obtrusive seismic method of multi-channel examination of surface waves is prominently used to draw out the shear-wave velocity profile (variation of soil with respect to its depth).

The geophysical technique known as Multichannel Analysis of Surface Waves, or MASW (Park et al., 1999) is a relatively new seismic characterisation method which utilises Rayleigh waves propagation. With MASW, the frequency dependent, planar travelling Rayleigh waves are created by a seismic source and then measured by an array of geophone receivers ...

In seismic engineering, the dynamic property of the soil is one of the most important aspects in ground response analysis. Dynamic property is significantly affected by local soil deposits. Shear wave velocity (V s) of soil is one of the main parameters in determining the amplification factor on ground surface.

Every geotechnical measurement requires geophysical methods to classify soil types under the ground. S-wave velocity (Vs), P-wave velocity (Vp), and density (ρ), are the most important parameters in the classification of soils. There are various methods to determine Vs, one of them is P-S logging method.

The shear wave velocity (VS) profile based on the dispersive characteristics of fundamental mode of Rayleigh type surface waves indicate underground stiffness change with depth as well as near surface stiffness. The most important utility of shear wave velocity (VS) is to estimate the liquefaction hazard potential of an area particularly in seismically

Lava-flow structure and morphology provide insights into eruption styles, emplacement mechanisms, and post-emplacement alterations like weathering. However, the challenge lies in quantifying subsurface structures of buried lava flows beneath soil and vegetation cover.
