This research uses shear-wave splitting, a method to measure anisotropy in seismic wave velocities, to understand mantle mineral alignment and deformation beneath the Hindu Kush-Pamir region, the western edge of the India-Eurasia collision zone. I have made new local S splitting measurements at the six stations of the Tajik network for earthquakes recorded since 2010, building on prior analysis of local S and teleseismic SK(K)S phases recorded by this network. In addition, I have measured splitting in local S and teleseismic SK(K)S, pSKS and sSKS phases at a new station, KBL. All splitting measurements are plotted in map view and 3D, which reveal the pattern of mantle deformation beneath this region.

Each year, Brown University showcases the research of its undergraduates at the Summer Research Symposium. More than half of the student-researchers are UTRA recipients, while others receive funding from a variety of Brown-administered and national programs and fellowships and go …
