The National Science Foundation awarded a $135,983 project grant under the Geosciences program (CFDA 47.050) to the University of the Incarnate Word for collaborative research titled "A Geochemical Approach to Quantifying the Magnitude of Strain and Fluid Flow Along the Subduction Interface." The research aims to characterize chemical and mechanical processes controlling the healing of subduction plate interfaces between large earthquakes through observations of ancient subduction zones now exposed on land and development of a numerical model. The university will conduct fieldwork and electron microscope analysis of samples to quantify mineral phases and redistribution with strain progression. The research seeks to address fundamental questions about magnitudes of volume and shear strain associated with interseismic deformation and the balance between dissolution and mineral precipitation. Insights will inform modeling of the effects of seismic slip, fluid flow, and interseismic strengthening on the spatial and temporal distribution of earthquakes at plate interfaces. The award period is from July 15, 2022 to June 30, 2025 and includes support for an early-career faculty member, PhD student, and nine undergraduates, six of whom will be recruited from the University of the Incarnate Word to serve the local Hispanic community.
