Project Grant R11AP81544

The U.S. Geological Survey (USGS) awarded Brigham Young University a $101,674.76 Project Grant under the Earthquake Hazards Program Assistance (CFDA 15.807) to improve methods for predicting liquefaction in gravelly soils during earthquakes. The key activities include conducting dynamic cone penetration tests and shear wave velocity measurements at sites in Alaska where sandy gravel layers have and have not liquefied in past earthquakes. This will expand the database of case histories to develop...

The National Science Foundation's Engineering program (CFDA 47.041) awarded a $200,000 Project Grant to the University of Delaware to evaluate liquefaction and its consequences through advanced field and laboratory investigations. The key objectives are to: 1) characterize subsurface features and mechanisms responsible for formation or abatement of liquefaction-induced ejecta at sites where conventional procedures misestimated its severity; 2) validate dynamic nonlinear effective-stress models...

This $310,085 National Science Foundation project grant will fund the development of a unified numerical framework for understanding co-seismic slope failures at complex sites. Funded under the Engineering program (CFDA 47.041), the two-year award made to Virginia Polytechnic Institute & State University will advance the fundamental understanding of earthquake-triggered slope failures and help predict, reduce, and mitigate their destructive consequences. The grantee will develop and validate...

The University of Texas at Austin received a $114,385 project grant from the National Science Foundation Division of Civil, Mechanical, and Manufacturing Innovation to investigate the liquefaction susceptibility of calcareous sand in Hawaii. The grant supports rapid response research from May 1, 2023 to April 30, 2024 under the NSF Engineering program (CFDA 47.041). Through this funding, UT Austin will characterize the strain-based liquefaction susceptibility relationship for Hawaiian calcareous...

This $1,000,000 Project Grant awarded by the National Science Foundation (NSF) under CFDA Program 47.041 (Engineering) supports research to study the dynamic behavior and liquefaction of gravelly soil deposits. The award aims to provide the first direct observations of the seismic and post-seismic responses of gravelly soils under controlled loading conditions. The research will determine the in-situ threshold shear strains for initiating nonlinearity, shear degradation, and liquefaction, as...

This National Science Foundation (NSF) Engineering (CFDA 47.041) Project Grant award, totaling $128,716, will support rapid response research by Georgia TECH Research Corp (the Office of Sponsored Programs) to characterize subsurface conditions and ground performance at sites affected by the 2023 Kahramanmaras, Turkey earthquake sequence. The goal is to develop well-documented case histories on building and infrastructure damage, with a focus on near-fault ground motions, liquefaction-induced...

This $566,155 five-year Project Grant from the National Science Foundation's Engineering program (CFDA 47.041) will support multiscale probabilistic characterization of seismic site response and its incorporation into system-level probabilistic seismic hazard assessments for water distribution systems. The awardee, North Carolina State University, will advance scientific knowledge of soil response to earthquake ground shaking at multiple scales through numerical modeling, geospatial analytics,...

The National Science Foundation (NSF) awarded a $163,118 Project Grant under the Integrative Activities program (CFDA 47.083) to the University of Maine System's University of Maine Division. This collaborative research project examines the effectiveness and durability of microbially induced desaturation (MID) to mitigate liquefaction in fine-grained, silt-based soils vulnerable to earthquake damage. The key objectives are to: (i) evaluate changes in excess pore water pressure due to MID to...

This Cooperative Agreement award from the National Institute of Standards and Technology (NIST) under the Measurement and Engineering Research and Standards (CFDA 11.609) program totals $289,243 and will be performed by the Regents of the University of Colorado (CU) from October 1, 2024 to September 30, 2027. The purpose of this award is to improve understanding of the impact of climate change-induced drought and heavy precipitation on soil dynamic behavior and its subsequent effect on the...

This $394,302 National Science Foundation project grant supports research at Purdue University to advance understanding and modeling of seismic cracking in earthen embankments and dams. Funded through the Engineering program (CFDA 47.041), the two-year Boosting Research Ideas for Transformative and Equitable Advances in Engineering Synergy project aims to validate assumptions around using static analyses to estimate earthquake-induced cracking location and size. Researchers will combine case...
