Joint ambient noise autocorrelation and receiver function analysis of the Moho

چکیده
SUMMARY In the field of seismic interferometry, cross-correlations are used to extract Green’s function from ambient noise data. By applying a single station variation method, using autocorrelations, we in principle able retrieve zero-offset reflections stratified Earth. These valuable as they do not require an active source and, being zero-offset, better constrained space than passive earthquake based measurements. However, studies that target Moho signals with autocorrelations often give ambiguous results unclear reflections. Using modified processing scheme and phase-weighted stacking, determine P-wave reflection time vertical autocorrelation traces for test known simple crustal structure (HYB Hyderabad, India). spite simplicity structure, show several phases related direct Although match some these additional qualitative way synthetic modelling, their presence makes it hard identify without prior knowledge. This knowledge can be provided by receiver functions. Receiver functions (arising mode conversions) sensitive same boundaries so should have high degree comparability opportunity combined analysis but themselves independently resolve VP, VS depth. timing suggested guide, observe S-wave on horizontal north component east component. The S is consistent PpSs–PsPs multiple, which also depends only velocity Finally, combine P HYB depth–velocity stacking gives us independent estimates found good agreement supplement obtain unique parameters. method portion EASI transect crossing Bohemian Massif central Europe, find approximate consistency depths determined spatial coherence between stations, thereby demonstrating applicable temporary deployments. application requires great care phase identification, has potential both average velocities alongside depth conjunction
