-I study the near-surface via seismic reflection surveying with shear-waves. I know that effective stress strongly influences the velocity behavior of any body wave in the near-surface (5 - 50 m). My question is this:
*Does effective stress influence SH (horizontally-polarized) or SV (vertically-polarized) shear-waves more? If you have an answer to this, please provide a citation/reference. Thanks in advance.
