What is a MASW? MASW is a shortcut of Multichannel Analysis of Surface Waves. The MASW method deals with surface waves in the lower frequencies (e.g.,1-30Hz) and uses a much shallower depth range of investigation ranges from a few meters to a few tens of meters. MASW deals with relatively lower frequencies and shallower investigation depth ... The first version of the SurfSeis software (v. 1.0) was released in 2000 for the application of the multichannel analysis of surface waves method on seismic data.. Developed at the Kansas Geological Survey (KGS), the MASW method consists of four main components (Miller et al., 1999): roll-along data acquisition, dispersion-curve imaging (Song et al., 1989; Park et al., 1998; Xia et al., 2007 ... The Tromino BLU is the newest model of the ENGY - a small, lightweight, 3-channel, all-in-one seismograph specifically designed for the dynamic characterization of subsoils with the highest accuracy and the lowest effort. This very adaptable device has applications for both geology and engineering ( modal analysis for structures ).

The tests were conducted using geometrics 24 channelled geode seismic recorder with seismograph as shown in Fig. 5.2.The vertical geophones with a natural frequency of 4.5 Hz (24 numbers) were used to receive the …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-011198 is an absorptive, ultra wideband single pole double throw (SPDT) switch with 1.8 dB of insertion loss at 44 GHz. The RF output ports are terminated in 50 Ω in the isolated paths. The power handling capability is 26 dBm. The input and output return losses are typically 18 dB. The logic levels areMultichannel analysis of surface waves (MASW) is a fast, low-cost, and environmentally friendly technique to estimate shear wave velocity profiles of soil sites. This paper introduces a new open-source software, MASWaves, for processing and analysing multichannel surface wave records using the MASW method. The software consists of …

The geometry of SCG-MASW is same as MASW, but surface wave dispersion is derived from short array stacked correlation gather instead of shot gather. Both theoretical and experimental data show that the SCG-MASW can improve the lateral resolution by using short receiving array, while not reducing the detection depth.MASW-Dispersion Analysis. During the very early stage of the surface wave method in 1950s and 60s of using a monotonic vibrator exciting at a single frequency (f) at a time, the. distance (Lf) between two consecutive amplitude maxima was measured by scanning the ground surface with a sensor. Then, corresponding phase.
