winMASW® Professional (winMASW®)

Main tools:

  • MASW (Multichannel Analysis of Surface Waves) analyses considering both Rayleigh and Love waves (and their joint inversion)
  • analysis of Rayleigh-wave attenuation to determine QS quality factors 
  • ReMi (Refraction Microtremors) analyses (passive seismics)
  • computation and modelling of the H/V spectral ratio (Nakamura’s method) to estimate the resonance frequency
  •  Vs30 calculation 
  • Band- Low- High-pass filters 
  • spectral analyses: computation of amplitude and phase spectra and spectrograms (frequency content over time) 
  • 1D modelling of refractions (also considering low-velocity layers) 
  • tool to combine two shots and simulate a dataset with a double number of channels (or three times, etc.) 
  • elastic moduli calculation tool 
  • ESAC analyses (but only for linear arrays, thus not fully exploiting the real ESAC technique active in the Academy version) 
  • tool for combining several traces acquired by a single 3-component geophone (using different offsets) and obtaining datasets useful for MASW analysis considering both Rayleigh (radial and vertical component) and Love waves
