Abstract
Seismic images of active fault zones can be used to examine the structure of faults throughout the crust and upper mantle, and give clues as to whether the associated deformation occurs within a narrow shear zone, or is broadly distributed through the lower crust. Limitations on seismic resolution within the crust, and difficulties imaging shallow structures such as the crust-mantle boundary (Moho), place constraints on the interpretation of seismic images. In this study we retrieve body wave reflections from autocorrelations of ambient seismic noise. The instantaneous phase coherence autocorrelations allow unprecedented ambient noise images of the North Anatolian Fault Zone (NAFZ). Our reflection profiles show a Moho reflected P-wave, and additional structure within the crust and upper mantle. We image a distinct vertical offset of the Moho associated with the northern branch of the NAFZ indicating that deformation related to the fault remains narrow in the upper mantle.
