The Seismology Section presented the following outstanding student paper awards at the AGU 1997 Fall Meeting in San Francisco, California, on last December.

Matthew J. Fouch presented a paper entitled “Shear Wave Splitting, Continental Roots, and Patterns of Asthenospheric Flow.” Matt received a B.A. in geology from Pomona College in Claremont, Calif., in 1993, and an Sc.M. in geophysics from Brown University in Providence, R.I., in 1996. He currently is completing a Ph.D. in geophysics at Brown under the supervision of Karen M. Fischer. In previous research at Brown, Matt examined seismic anisotropy and mantle flow in the southern Kuril, Japanese, Izu-Bonin, and Mariana subduction zones through modeling of observed shear wave splitting. More recently, his research has focused on constraining the structure and deformation of the sub-continental mantle using a combination of seismic observations and numerical methods. In this work, Matt has developed numerical models of predicted shear wave splitting from asthenospheric flow around a continental root. Using these models, he has estimated the possible lithospheric and asthenospheric contributions to seismic anisotropy for eastern North America.
