    Abstract

    We present a way of characterizing the structure beneath a seismic station, by exploiting stacked correlograms of three-component records from teleseismic events. This seismic daylight imaging approach exploits the extraction of reflection and conversion information from teleseismic coda via tensor autocorrelation. The approach is illustrated for a number of Australian stations in a variety of tectonic environments using hundreds of teleseismic events, to extract P and S reflectivity and converted Ps and Sp information. The results show a very good agreement with prior knowledge across Australia. Compared with the classical receiver function, the broader-frequency band of 0.5–4.0 Hz provides additional information on finer-scale structure.
