Phil Resor, assistant professor of earth and environmental sciences, received a $246,728 grant from the National Science Foundation for his study on "Three Dimensional Characterization of a Pseudotachylyte-bearing Fault." The grant was awarded on March 15 and expires on June 30, 2014. In this study, Resor and Wesleyan students will use high-resolution x-ray computed tomography imagery of natural and experimental fault surfaces to quantify surface roughness, frictional contact area, and Pseudotachylyte fault rock thickness. "Pseudotachylytes are generally considered the only unequivocal evidence of earthquake slip velocities that is preserved in fault zones," Resor explains. The proposed project will improve the…
