Depth of Moho derived from receiver functions in relation to coda attenuation parameters in Croatia

Seismic waves contain information about source and medium characteristics through which elastic waves propagate. Receiver function analysis provide a method in which teleseismic body waves are used to extract just the effect of the structure beneath the seismic station and discard influences from the source and path parts in which we are not interested in. We used it here to determine the crustal thickness, i.e. the depth of the Mohorovičid discontinuity (Moho). On the other hand, coda waves of local earthquakes are used to estimate the average attenuation in the form of the coda-Q factor (Qc) in the volume around seismic station. Qc was estimated using the single backscattering model. Qc is frequency (f) depended and is usually written as Qc=Q0fn. We want to determine if there is any correlation between Q0 or n and the Moho depth as some studies suggest. For this we use results from the two previously mentioned methods applied to seismograms recorded by seismic stations of the Croatian Seismological Network.
