This National Science Foundation (NSF) Division of Earth Sciences Project Grant, awarded to the University of California Santa Cruz (UCSC), aims to advance the understanding of subduction fault and earthquake mechanics. Through a combination of new experiments on subduction zone rocks and numerical modeling, the project will investigate how the rheology (deformation behavior) of the megathrust fault zone, and the heterogeneity within it, affect fault slip behavior. Additionally, the project will examine how inelastic deformation on and off the fault impacts strain energy accumulation and the distribution of locking and slip. The $270,793 award, effective from January 1, 2024 to December 31, 2026, supports the training of early career scientists, including undergraduate and graduate students, postdocs, and two early career principal investigators. The project will also develop a modeling short course on subduction zone rheology, with the course materials made publicly available as instructional videos to maximize accessibility. This work falls under the NSF's Geosciences program (CFDA 47.050), which aims to expand fundamental knowledge and understanding of the integrated Earth system through basic research in the atmospheric, earth, and ocean sciences.
