Stacked P-to-S and S-to-P receiver functions determination of crustal thickness, Vp, and Vs: The H-V stacking method
Stacked P-to-S and S-to-P receiver functions determination of crustal thickness, Vp, and Vs: The H-V stacking method
H-? stacking is a routine method for determining crustal thickness (H) and Vp/Vs (?) using P-to-S (Ps) receiver functions. In this paper we show that S-to-P (Sp) receiver functions may also be used to determine crustal parameters. Sp provides independent information, complementary to Ps. We develop a method called H-V (crustal thickness-velocity) stacking where Ps and Sp receiver functions are stacked, to jointly determine seismic crustal parameters (H, Vp, and Vs) beneath a given seismic station. We demonstrate the utility of the H-V stacking method using data from seismic station HYB (Hyderabad) on the Dharwar Craton. We estimate a crustal thickness of 34.5?km, Vp?=?6.55?km/s, and Vs?=?3.85?km/s beneath the station in good agreement with previous results. The strength of the H-V method is that it requires no assumptions about elastic parameters and/or additional processing or methodology.

Abstract
H-? stacking is a routine method for determining crustal thickness (H) and Vp/Vs (?) using P-to-S (Ps) receiver functions. In this paper we show that S-to-P (Sp) receiver functions may also be used to determine crustal parameters. Sp provides independent information, complementary to Ps. We develop a method called H-V (crustal thickness-velocity) stacking where Ps and Sp receiver functions are stacked, to jointly determine seismic crustal parameters (H, Vp, and Vs) beneath a given seismic station. We demonstrate the utility of the H-V stacking method using data from seismic station HYB (Hyderabad) on the Dharwar Craton. We estimate a crustal thickness of 34.5?km, Vp?=?6.55?km/s, and Vs?=?3.85?km/s beneath the station in good agreement with previous results. The strength of the H-V method is that it requires no assumptions about elastic parameters and/or additional processing or methodology.
