Current Research in EEPS: Dr. Fan-Chi Lin, University of Utah

Since its development over a decade ago, ambient noise tomography has become a standard tool to image detailed crustal structure. Taking the advantage of continuous background vibration, robust surface wave signals can be extracted from inter-station noise cross-correlation functions. While early studies had mostly focused on surface wave group and phase dispersion measurements, recent studies have shown that reliable amplitude measurements can also be made by carefully performing noise preprocessing. More specifically, Rayleigh wave ellipticity, which is most sensitive to shallow crustal structure, can be measured based on the amplitude ratio between multi-component cross-correlations. By taking the advantage of complimentary depth sensitivities of ambient noise and earthquake surface wave measurements as well as teleseismic receiver functions, detailed lithospheric structure can be imaged from shallow to deep. Combining with the densely distributed broadband and geophone seismic arrays, robust 3D models can be constructed on a variety of different scales. These models provide new insight into the regional tectonics, seismic hazard, and geothermal resources. In this presentation, I will review some of the studies our group has involved over the last five years since my last Rice visit. The area of interest includes various locations in the western US, Alaska, and Taiwan.

For outside visitors, the best way to get to our department is to come in on Rice Blvd and turn left into entrance 20 (intersection of Rice and Kent St.). At the stop sign, you will see a visitor parking lot on your right.  From there, walk east to the department.  The google map below shows exactly where our building is.
