Figure on the left shows S velocity profiles obtained from inversion of RFs from station KSM. Red line (left) shows the Vp/Vs ratio result from inversion and red model (right) is the best fit model. The coloured section shows the best 1000 models and the red arrow shows possible Moho depth. The result obtained from the inversion estimated the Moho to be around -27 km, which is consistent with the H-k stacking method. Figure on the top right shows the fitting between observed (black) and predicted (blue) receiver function from the inversion. CC BY
