This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to characterize borehole breakouts in anisotropic materials, both in the laboratory and in natural settings. The $180,350 award to Carleton College will involve two primary research methods: 1) physical experiments using analog materials like sand, gelatin, and wax to investigate how rock layering and anisotropy impact breakout formation, and 2) analysis...
This Project Grant award from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support collaborative research to investigate seismic cycle processes in the "earthquake critical zone" - the upper 1 km of fault zones where seismic waves, rocks, fluids, and the built environment intersect. The $277,792 award to Brown University, with a period of performance from September 1, 2024 to August 31, 2029, will fund research on two major continental strike-slip...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) supports a collaborative research project between the University of California, Santa Cruz (UCSC) and Hebrew University to directly measure fault rupture dynamics and seismic wave propagation in a laboratory setting. The $399,601 award, effective from August 1, 2024 to July 31, 2027, will leverage specialized laboratory equipment to conduct high-speed imaging and in-situ seismogram...
This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports a collaborative research effort between California State University San Bernardino and the University of Cincinnati. The $354,304 award aims to recruit junior-level university students and sophomore-level community college students into geosciences educational and career tracks through year-long, cohort-based, authentic geologic research experiences. The research activities focus...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) totaling $225,816 will support collaborative research to investigate the evolution of elastic wave properties during the seismic cycle. The primary objectives are to explore whether variations in seismic wave properties can be identified before and/or after earthquakes, determine the underlying physical mechanisms, and assess the potential for operational forecasting of ruptures on meter-scale...
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 Project Grant award of $153,335 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research effort to observe and study the frictional interfaces that control large-scale hazardous phenomena like earthquakes and ice sheet collapse. The research team, led by the University of California, Santa Cruz, will use advanced imaging and acoustic sensing techniques to directly observe the microscopic contacts and slip dynamics at these interfaces in...
This $213,696 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award will support research to gain new insights into the subsurface magma reservoirs below Hawaii. The project will use seismic data and modern imaging techniques to determine the depth, dimensions, and melt fraction of magma storage zones, and explore the relationship between magma migration and seismic activity. The research will be conducted by the University of Illinois, with a PhD student...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $125,519 to Cornell University to conduct collaborative research on understanding the evolution of frictional interfaces in systems like earthquakes and ice sheet collapse. The goal is to directly observe how microscopic contacts at rock or ice interfaces control friction and hazardous large-scale behaviors in these systems. The research will use a custom cryogenic biaxial apparatus and ice...
The National Science Foundation awarded a $135,983 project grant under the Geosciences program (CFDA 47.050) to the University of the Incarnate Word for collaborative research titled "A Geochemical Approach to Quantifying the Magnitude of Strain and Fluid Flow Along the Subduction Interface." The research aims to characterize chemical and mechanical processes controlling the healing of subduction plate interfaces between large earthquakes through observations of ancient subduction...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $206,119 to Iowa State University of Science and Technology to conduct collaborative research on characterizing borehole breakouts in anisotropic materials. The project uses two research methods - physical experiments and analysis of well log data - to study how rock layering and anisotropy impact the inference of stress directions from borehole breakouts. The research aims to improve the understanding of stress conditions near the San Andreas Fault, which is important for estimating earthquake hazards. The project will train one graduate student and multiple undergraduates, and develop educational materials for high school students. No sub-awards are planned under this award, which has a performance period from September 1, 2024 to August 31, 2026.
