Common-reflection-point-based prestack depth migration for imaging lithosphere in Python: Application to the dense Warramunga array in northern Australia

Sun, Weijia; Kennett, Brian


We exploit estimates of P‐wave reflectivity from autocorrelation of transmitted teleseismic P arrivals and their coda in a common reflection point (CRP) migration technique. The approach employs the same portion of the vertical‐component seismogram, as in standard Ps receiver function analysis. This CRP prestack depth migration approach has the potential to image lithospheric structures on scales as fine as 4 km or less. The P‐wave autocorrelation process and migration are implemented in...[Show more]
