Session 3.3 ______ ___ GNGTS 2023 Fig. 2 (a) The estimated DCs clustered into two sets. (b) The location of the clustered DCs. (c) The estimated W/D relationships for the two clusters. (d) The estimated apparent Poisson’s ratio of the two clusters. (e and f) Iso-surfaces of the estimated VS and VP from W/D method. The sections are at plains x= 600 m, y = 400 m, and depth = 70, and 125 m. Fig. 3 The difference between the estimated VS and VP models obtained from the W/D, LCI and SWT methods using equation 1. (a,b) W/D versus LCI. (c,d) W/D versus SWT. Acknowledgements We would like to thank Gallego Technic Geophysics for licensing the field data.
