Crustal surface-wave velocity structure of the east Albany-Fraser Orogen, Western Australia, from ambient noise recordings

Sippl, Christian; Kennett, Brian; Tkalcic, Hrvoje; Gessner, Klaus; Spaggiari, Catherine


Group and phase velocity maps in the period range 2-20 s for the Proterozoic east Albany-Fraser Orogen, Western Australia, are extracted from ambient seismic noise recorded with the 70-station ALFREX array. This two-year temporary installation provided detailed coverage across the orogen and the edge of the Neoarchean Yilgarn Craton, a region where no passive seismic studies of this scale have occurred to date. The surface wave velocities are rather fast overall (>3 km/s nearly everywhere), as...[Show more]
