H-k Stacking Method by Zhu and Kanamori (2000)
Figure shows an example H-k stacking result for
station KSM.
A total of 865 receiver functions (RFS) are used
in the stacking from 12 years of data.
Input:
865 RFs
Assumed crustal bulk Vp: 6.3 km/s
- 0.0
Output:
-0.1
-0.2
Moho thickness estimate: 28.5 km
Crustal bulk Vp/Vs ratio estimate: 1.66
Black points show bootstrapping solutions for
randomly selected and stacked RFs.
The bootstrapping solutions show that results
obtained from the full stacking of RFs are robust,
with small error estimates; depth= +- 2km and
Vp/Vs= +-0.04.
This varies from station to station depending on
local or regional tectonic complexity.
