SUMMARY<\/strong><\/p>\n

I am interested in relating upper mantle structure and anisotropy to the tectonic features seen at the surface of the Earth. I\u00a0participated in the installation of an array of broadband seismometers across two transects in the\u00a0<\/span>Oregon High Lava Plains\u00a0during my postdoc at Arizona State University (<\/span>pictures taken by Maureen Long\u00a0here<\/a>) as part of the\u00a0HLP<\/a>\u00a0project. Undergraduate student Helen Feng and I have been analyzing seismic data collected by these stations and by USArray stations. We measured surface wave dispersion in order to model seismic anisotropy in the region. The High lava Plains, which lie in the northern and less extended part of the Basin and Range Province, have been volcanically very active in the late Cenozoic, but the origin of this large volume volcanism is still unclear. Since seismic anisotropy may be a signal of mantle deformation, this study will help us understand the deformation mechanisms taking place in the upper mantle in that area and will shed light on the nature and origin of the volcanism.<\/p>\n
