Vp/Vs RATIO
Neighbourhood Algorithm (NA-sampler)
NA is used to produce a seismic velocity profiles by inversion of the RFS and also to
show the robustness the Moho depth estimate.
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.
