La técnica de Análisis Multicanal de Ondas Superficiales (MASW) es un método que analiza las propiedades de propagación de las ondas sísmicas superficiales (Vs), principalmente las Ondas de Rayleigh, las cuales se propagan horizontalmente desde la fuente emisora hasta los geófonos receptores. MASW, an in-situ non-destructive method, uses frequency-dependent properties of horizontally travelling surface waves (Rayleigh) to visualize and characterize sub-surface lithology . In this study, an MASW setup consisting of 24 geophones of 4.5 Hz Natural frequency and a 24-channel geode seismograph has been used to obtain a 2D V …

The MASW is a multichannel extension of a widely used surface wave method called the Spectral Analysis of Surface Waves that generally uses a two-receiver approach [55, 68]. The merits and wider range of applications of the MASW and MAM methods in geotechnical & earthquake engineering have been well documented ([ 18 , 22 , 28 , 29 , …Metode MASW merupakan metode yang memanfaatkan fenomena dispersi gelombang permukaan yang bertujuan untuk mengevaluasi karakter suatu medium solid.Product from MASW Surveys Final product from an MASW survey is the subsurface variation of shear-wave velocity (Vs) in 1-D (depth) (Figure 1), 2-D (depth and one surface direction) (Figure 2), and 3-D (depth and two surface directions) (Figures 3 and 4) formats. The shear-wave velocity (Vs) most closely

great plains mcpherson ks 4000-4009. A summary of the entire procedure with a MASW method (active or passive) is displayed in the flowchart in Figure 2.
