The National Science Foundation (NSF), through its Geosciences program (CFDA 47.050), awarded a $272,664 project grant to the University of Texas at Austin to conduct collaborative research on subduction megathrust rheology. The research aims to quantify how the deformation behavior and spatial heterogeneity of subduction zone rocks affect fault slip behavior, including the occurrence of slow earthquakes and slip events. The project will involve new laboratory experiments on subduction zone rocks under relevant pressure and temperature conditions, and the experimental data will inform numerical models bridging scales to incorporate fault zone heterogeneity. The research findings are expected to provide new insights into the roles of rheology and spatial heterogeneity in controlling strain energy accumulation and the occurrence of locking and slip in subduction systems. This 3-year project, running from January 1, 2024 to December 31, 2026, will support the training of early-career scientists and develop an accessible short course on subduction zone rheology modeling.
