This National Science Foundation (NSF) Frontier Research in Earth Science (FRES) Project Grant, awarded under the Geosciences program (CFDA 47.050), provides $126,858 in funding to Brown University to investigate how the "earthquake critical zone" impacts seismic processes, with the goal of improving earthquake hazard models and site response analyses. The 5-year project will bridge geoscience and engineering concepts, data, and models to characterize the material properties of two...
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 Project Grant of $290,439 supports research at Brown University from November 1, 2022 to August 31, 2027 under the Geosciences program (CFDA 47.050). The award will fund collaborative research integrating observational, experimental, and modeling efforts to characterize the full-spectrum rheological response of Earth's mantle and illuminate underlying microphysical processes controlling viscoelasticity. Observational work will characterize frequency-dependent...
Brown University was awarded a $422,170 Project Grant from the National Science Foundation Division of Earth Sciences on May 15, 2021 to support research titled "Experimental Constraints on the Rheology of the Mantle Lithosphere at the Base of the Seismogenic Zone." The award has a completion date of April 30, 2024. The research is being conducted under the NSF's Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through basic...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $125,519.00 to Cornell University to conduct collaborative research on observing the evolution of frictional interfaces, such as those found in earthquake faults and glacial systems. The goal is to use experimental methods like total internal reflection imaging and acoustic sensing to directly observe how the microscopic contacts at these interfaces change during shear, slip, and stability,...
This $238,111 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund research at Harvard University from August 2022 through July 2025 to develop an understanding of the factors controlling ground surface deformation during thrust and reverse fault earthquakes. Through discrete element modeling, the researchers will generate over 6,000 two-dimensional models and additional three-dimensional models to statistically assess how fault and sediment parameters...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $153,335.00 to the University of California, Santa Cruz to conduct collaborative research on the dynamics of frictional interfaces, which are relevant to understanding hazards posed by earthquakes and ice sheet collapse. The goal is to directly observe the coupled processes that control the evolution of frictional interfaces, such as nucleation, slip, healing, and melting, using a custom...
This two-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $174,000 to fund research examining the interplay between fault material strength, roughness and friction at various scales. The award will support work conducted between June 2021 through May 2023 in Santa Cruz, California. As part of its mission to strengthen the national scientific enterprise's understanding of the integrated Earth system, the Geosciences program aims to expand...
