This $173,614 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to reconcile geophysical observations of slow slip and tremor with geologic and rheological constraints in subduction zones. The project aims to: (1) investigate the types of rocks that potentially hosted slow slip and tremor by analyzing their mineral properties, and (2) compare the rock record to geophysical imaging of modern subduction zones. The research involves integrating field-based analysis, geochronology, geochemistry, structural geology, and rheology to better understand the geological conditions and slip behavior at the base of the seismogenic zone. This work will inform observations of slow slip and tremor in active subduction zones and improve geodynamic models of the seismic cycle and associated earthquake hazards. The award was made to Louisiana State University, with the project scheduled for completion by December 31, 2027. No sub-awards are planned under this grant.
