This Project Grant award for $125,519, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort to directly observe the coupled processes that control the evolution of frictional interfaces in both earthquake fault systems and glacial ice sheets. The primary research goal is to improve the understanding of how microscopic contacts and their evolution during shear, slip, and stability cycles govern the large-scale behaviors of these...
The National Science Foundation awarded a $368,201 Project Grant to the Regents of the University of Minnesota under the Geosciences program (CFDA 47.050) to conduct collaborative research towards developing a new framework for interpreting mantle deformation. Over the five-year period from September 2022 to August 2027, key products and services will include integrating observational, experimental, and modeling efforts to characterize the full-spectrum rheological response of Earth's mantle and...
This $518,605 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund collaborative research to quantify strain and fluid flow along subduction interfaces. Penn State University will lead efforts to characterize chemical and mechanical processes controlling the healing of subduction zones between large earthquakes. Researchers will study ancient subduction exposures in Japan and Alaska spanning depths of 8-20 km and temperatures of 150-350°C. Electron...
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...
The National Science Foundation (NSF) awarded a $206,021 Project Grant under the Geosciences program (CFDA 47.050) to Utah State University (USU) to conduct collaborative research on the evolution of elastic wave properties during the seismic cycle. The project aims to illuminate the processes associated with earthquake precursors in order to improve seismic hazard forecasting. The research will use active source seismic interrogation techniques to study the mechanics of pre- and post-seismic...
This $153,335 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to observe and study the evolution of frictional interfaces in geological systems. The goal is to better understand the fundamental mechanisms driving the evolution of unstable frictional interfaces, which is critical for assessing hazards related to earthquakes and ice sheet collapse. The research team, led by the University of...
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...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $258,297 to the Colorado School of Mines to conduct research on the micromechanics of fault zones and the deformation of earth materials, particularly fault gouge. The research aims to develop realistic computational models to better understand how the complex heterogeneity and frictional characteristics of fault gouge influence fault rupture, critical zone factors, and transport...
