Abstract
Earth holography was applied to Norwegian Seismic Array (NORSAR) earthquake P-wave recordings. Simulation of the NORSAR sensor configuration indicates that a satisfactory reconstruction of the essential features of an embedded body is feasible with a depth resolution which seems to be better than that attained using more traditional time and amplitude inversion schemes. The earth holography concept was tested using NORSAR recordings of three deep earthquakes at teleseismic distances. The results indicate lithospheric heterogeneous bodies with a significant vertical extent. The most pronounced scattering features of these inhomogeneities are located at depths around 100, 148 and 212 km.
