This $550,014 Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences federal grant program (CFDA 47.050), will fund research at Arizona State University to advance understanding of the influence of subducted slabs on thermal and chemical heterogeneities in Earth's lowermost mantle. The awardee will perform high-resolution thermo-chemical modeling using supercomputing to simulate the variable behaviors and interactions of subducted tectonic plates...
This $393,670 National Science Foundation award under the Geosciences program (CFDA 47.050) funds research at the University of California, Davis from March 2022 through February 2025 to test the role of metastable olivine in subduction dynamics and deep earthquakes. The researchers will use state-of-the-art numerical simulations integrating experimental and observational parameters to model various subduction scenarios with and without the presence of metastable olivine. They will compare model...
This $355,607 Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) supports collaborative research to investigate an ancient example of flat-slab subduction in southern California and western Arizona. The goal is to collect data from rocks that were once located above the descending oceanic plate in order to improve simulations and understanding of similar modern tectonic settings, many of which pose significant...
This five-year, $252,329 National Science Foundation project grant funds research towards developing a new framework for interpreting mantle deformation. The grantee, the University of California Santa Barbara under the NSF's Geosciences program (CFDA 47.050), will integrate theory, experiments, and observations spanning seismic to convective timescales. Researchers will characterize frequency-dependent upper-mantle dissipation in three locations using seismic and geodetic observations....
This $174,000 two-year project grant from the National Science Foundation Division of Earth Sciences aims to advance understanding of episodic tremor and slip in subduction zones. Funded under the Geosciences program (CFDA 47.050), which supports basic research to strengthen knowledge of the integrated Earth system, this award will fund research into the role of metasomatic alteration in subduction zone seismic phenomena from September 2021 through August 2023. The grantee, located in Seattle,...
This $119,779 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: Investigate the types of rocks that potentially hosted slow slip and tremor by analyzing mineral composition, age, chemistry, and deformation, and Compare the rock record to geophysical imaging of modern...
This five-year, $283,849 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research at Brown University to develop a new framework for interpreting mantle deformation through an integrated approach combining theory, experiments, and observations across seismic to convective timescales. Key products include observational work characterizing frequency-dependent upper-mantle dissipation in three locations using seismic and geodetic data; experimental...
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...
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...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund a collaborative research project focused on reconciling geophysical observations of slow slip and tremor with geologic and rheological constraints in subduction zones. The $173,614 award to Louisiana State University, which will run from January 15, 2025 to December 31, 2027, aims to: Investigate the types of rocks that potentially hosted slow slip and tremor by analyzing the minerals,...
