- The National Science Foundation Office of Integrative Activities awarded Arizona State University $176,810 on August 1, 2026, under the Geosciences program (CFDA 47.050) to conduct collaborative research on the structural and thermal architecture of the North American Cordillera in southeastern California. The project integrates field observations, laboratory analyses, and structural and thermal modeling to reconstruct the tectonic and thermal history of mountains near the California-Arizona...
- The National Science Foundation Division of Ocean Sciences awarded Northern Arizona University $358,360 under the Geosciences program (CFDA 47.050) on April 15, 2026, to calibrate and standardize amino acid racemization (AAR) geochronology for marine mollusk shells as a dating method for ancient shorelines. The recipient will analyze D/L ratios from approximately 100 globally distributed Last Interglacial sites (approximately 125,000 years old) to establish temperature-dependent isochrons and...
- The National Science Foundation Division of Ocean Sciences awarded the University of California Santa Cruz $357,000 on September 1, 2026, under the Geosciences program (CFDA 47.050) to investigate fault slip associated with the 2011 Tohoku-Oki earthquake. The work analyzes fault-zone samples recovered from hundreds of meters below the seafloor at three core sites on the plate boundary fault. The sites are 30 meters apart but show fault-zone thickness varying from 1 to 15 meters. Using trace...
- The National Science Foundation Office of Integrative Activities awarded Woods Hole Oceanographic Institution $428,486 on September 1, 2026, under the Geosciences program (CFDA 47.050) to establish relationships between tectonic features and seismic hazards at subduction zones. The research uses state-of-the-art plate tectonics models and mathematical methods to map connections between seafloor tectonic structures and earthquake locations at subduction zones, with initial focus on the Aleutians,...
- The National Science Foundation Office of Integrative Activities awarded Utah State University $355,007 on January 1, 2027, under the Geosciences program (CFDA 47.050) to conduct integrated experimental and modeling research on subduction zone earthquake controls through December 31, 2029. The project develops a system to distinguish whether subduction zone faults build energy for infrequent large earthquakes and tsunamis or release stress through small events and slow sliding. Research measures...
- The National Science Foundation awarded a $305,251 Project Grant to the University of Arizona under the Geosciences program (CFDA 47.050) to conduct research examining metamorphic rocks from ancient subduction zones in the Baja California peninsula from September 1, 2022 to August 31, 2025. The research aims to quantify the pressure-temperature-time histories of amphibolite, blueschist, and eclogite rocks using advanced thermobarometry and petrochronology techniques to better understand the...
- The National Science Foundation awarded $241,402 under the Geosciences federal grant program (CFDA 47.050) to the University of Arizona for a collaborative research project grant running from July 1, 2023 to June 30, 2025. The University of Arizona, in coordination with European scientists, will analyze seismic data collected in northern Ecuador between 2020 and 2022 to generate detailed 3D images of the subduction zone geology beneath the country. Using machine learning techniques, the...
- The National Science Foundation Office of Integrative Activities awarded Northern Arizona University $568,582 on November 1, 2026, under the Geosciences program (CFDA 47.050) to operate a Research Experiences for Undergraduates (REU) site focused on remote sensing of Earth and environmental systems through October 31, 2029. The award funds an REU site that provides undergraduate students selected from across the United States with hands-on research opportunities in terrestrial remote sensing...
- 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...
The National Science Foundation Division of Ocean Sciences awarded Northern Arizona University $450,000 on September 1, 2026, under the Geosciences program (CFDA 47.050) to map bending faults at subduction zones globally and understand variability in their spacing and magnitude. The project will identify and characterize bending faults—faults formed as oceanic plates bend during subduction—using automatic fault-mapping tools applied to multibeam bathymetry data at all locations globally with high-quality seafloor bathymetry. Detailed fault characterization at select locations will be complemented by seismic reflection data analysis. The investigators will produce data products formatted for integration with other marine geophysical and geological datasets, making fault maps accessible for viewing alongside complementary data. Results will inform understanding of earthquake and tsunami processes at subduction zones and the deep water cycle, as seawater infiltration through bending faults into the crust and upper mantle affects subduction zone mechanics and forearc deformation. The project will provide training and research opportunities to graduate students and undergraduate cohorts. Work is performed in Flagstaff, Arizona, with a period of performance from September 1, 2026, through August 31, 2029. No sub-awards are planned. Northern Arizona University is a public research institution and Hispanic-Serving Institution; the award flows through Arizona Board of Regents as the parent entity.
