- The National Science Foundation Division of Earth Sciences awarded $275,144 to the Regents of the University of Minnesota on February 1, 2027, under the Geosciences program (CFDA 47.050) to conduct collaborative research bridging mineral microscale physics to tectonic macroscale deformation. The research develops and applies a framework for upscaling between the microscale of mineral crystal defects and grain evolution, the mesoscale of mineral phase interactions and petrological mixing, and the...
- The National Science Foundation Office of Integrative Activities awarded Utah State University $355,007 on January 1, 2027, under the Geosciences program (CFDA 47.050) to conduct integrated experimental and modeling research on subduction zone earthquake controls through December 31, 2029. The project develops a system to distinguish whether subduction zone faults build energy for infrequent large earthquakes and tsunamis or release stress through small events and slow sliding. Research measures...
- The National Science Foundation Division of Earth Sciences awarded a $235,444 Project Grant to Indiana University under the Geosciences federal grant program (CFDA 47.050) for the period of September 1, 2021 through August 31, 2026. The grant supports collaborative research toward developing an integrated modeling framework for physics-based estimates of megathrust rupture potential. The Geosciences program aims to strengthen understanding of the integrated Earth system through basic research in...
- The National Science Foundation Division of Earth Sciences awarded the University of Utah $210,713 on January 1, 2026, under the Geosciences program (CFDA 47.050) to conduct experimental research assessing the roles of wear and roughness on dynamic fault friction. The project will advance earthquake physics through controlled laboratory experiments using a specialized deformation apparatus to explore mechanisms regulating fault friction during seismic slip. The work includes experimental...
- The National Science Foundation Division of Earth Sciences awarded the University of Illinois a $127,723 Project Grant under the Geosciences federal grant program (CFDA 47.050) to conduct collaborative research on interpreting mantle deformation from September 2022 through August 2027. The University will integrate theory, experiments, and observations spanning seismic to convective timescales to better understand the Earth's mantle rheological response and the underlying microphysical processes...
- 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...
- This National Science Foundation (NSF) Division of Earth Sciences Project Grant awarded to the Planetary Science Institute will conduct collaborative research to study the deformation behavior and rheology of subduction zone rocks. The $169,023 award, made under NSF's Geosciences (CFDA 47.050) program, will address two key questions: 1) how the heterogeneous rheology along subduction megathrusts affects fault slip behavior, and 2) how inelastic deformation on- and off-fault impacts strain energy...
The National Science Foundation Division of Earth Sciences awarded Iowa State University of Science and Technology $402,989 on August 1, 2026, under the Geosciences program (CFDA 47.050) to conduct laboratory experiments simulating deformation in subduction zones. The research will combine brittle and ductile materials in controlled experiments to replicate the conditions where tectonic plates move beneath one another, recording acoustic emissions when material fractures during deformation. By varying the placement and proportion of breakable material, the researchers will document how material breaks under stress and connect laboratory deformation patterns to signals detectable through seismic monitoring methods. The findings will improve understanding of how creep events relate to earthquakes in subduction zones, directly supporting earthquake risk assessment models. Performance occurs at Iowa State University in Ames, Iowa through July 31, 2029. The project will train graduate and undergraduate students in geology, science visualization, and illustration, and provide high school students research internship opportunities.
