Techniques for Imaging the Top Layer in SeisImager/SW (MASW)
While "crack top" is not a standard, official term in the SeisImager user manual , in the context of high-resolution geophysical surveys, it refers to the .
Successfully imaging the "top" of your velocity model in SeisImager requires a combination of high-frequency data collection and careful inversion strategy. By utilizing smaller geophone spacings, focusing on higher frequency phase velocities in WaveEq, and utilizing thin, low-velocity, initial-model layers, you can significantly improve the accuracy of the top few meters of your shear wave profile. seisimager crack top
For analyzing surface wave data or detecting subsurface anomalies like "cracks" (fractures) using SeisImager , the most useful reports and resources focus on 2D shear-wave velocity (Vs) profiling fracture compliance Key Technical Reports and Manuals SeisImager/SW Manual
Tomography is typically better than delay-time methods for mapping shallow, complex, or varying velocities, particularly in the top layer. Use the tomography module for smoother, more precise shallow resolution. Best Practices and Troubleshooting "Impossible" Data Techniques for Imaging the Top Layer in SeisImager/SW
