Lava flow layers and \(V_s\) model at the Baner Hill Site. (a) Schematic diagram illustrating the lava flow geometry in the survey area based on an outcrop exposed in a nearby quarry. Quarry location is shown in Supplementary Figure S1. (b) Shear wave velocity profile. (c) Histogram representation of data misfit for the first and final inversion iterations along with a normal distribution fitted to the last iteration misfit. (d) Uncertainty estimates in the inverted velocity profile. Supplementary Figure S9 shows an overlay image of the velocity model and schematic basalt flow layers for the selected inset.
