2 Crust, Moho

3 Crustal Structure (Model)

4 Integrated: Integrated: - Receiver Function - Gravity - Magnetic - Pre-existing seismic models

5 RF A receiver function is the seismic response of the earth beneath a seismic station to an incoming P-wave. The physical earth property that controls what is observed in a receiver function is the P-to-S impedance structure A receiver function is the seismic response of the earth beneath a seismic station to an incoming P-wave.
