In the Shreedharan Lab in Utah State University's Department of Geosciences, graduate students, from left, Sapana Regmi and Lindsey Broderick, perform a shear test on a load frame to measure the shear strength of a tiny rock sample. A goal of the NSF-funded research is to improve earthquake modeling. Credit: M. Muffoletto
