6/3/2023 0 Comments Seisimager crack![]() Borehole data such as P-wave velocities and blow counts (N-values) can also be correlated. SeisImagerSW also allows the user to build models and examine the effects of velocity variations. ![]() ![]() MAM frequency Vs phase velocity dispersion curve. The wizard-driven processing package steps users through each stage sequentially and offers tool tips for each parameter. Alternatively, 2D active source profiles can be processed and inverted from either rolling through a fixed spread, or adoption of a lanstreamer. Higher frequency data from a sledgehammer source can be combined with lower frequency data from microtremors to produce one high-resolution plot of S-wave velocity. SeisImagerSW includes both active source and passive source data analysis capability in an easy to use package. Multi Channel Analyses of Surface waves was introduced at the start of the 21st central and has subsequently become a staple methodology for UBC/IBC Vs30/Vs100 site classification and stratigraphic investigation. Surface waves are easy to record and loaded with information about the structural composition of the subsurface. SeisImagerSW is a robust and comprehensive processing package for determination of shear-wave velocity (Vs) through analysis of active source and passive source (microtremors) surface waves.
