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 awarded a $174,000 Project Grant to Providence, Rhode Island for work investigating the competition between thermal pressurization and dilatancy on rough surfaces at earthquake slip rates. This funding supports a two-year research project under the Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the award will allow investigation...

This National Science Foundation Project Grant award of $139,678 supports research into the influence of fault geometry on shallow frictional sliding in subduction zones under the Geosciences program (CFDA 47.050). The awardee, Planetary Science Institute, will conduct complementary theoretical and numerical analyses to determine how fault zone geometry controls the sliding stability of thrust faults and how shallow slip events nucleate and propagate within a subduction zone fault network over multiple seismic cycles. Specifically, the researchers will investigate the effects of fault network geometry and frictional properties on potential ruptures, exploring whether interactions between faults and with the seafloor can generate the observed range of behaviors in subduction zones. They will use innovative analysis and numerical simulations combining with a new technique to include the effects of typical wedge-shaped shallow subduction zone geometry. This work will provide insights into the relationships between shallow fault behavior and large megathrust earthquakes to help assess seismic and tsunami risks. The award period is from November 1, 2022 through January 31, 2024.
