The award funds deployment of broadband ocean bottom seismographs in the Eastern Aleutian Subduction Zone, augmenting permanent land stations across a region transitioning from continental...
- The Woods Hole Oceanographic Institution was awarded a $364,098 Project Grant from the National Science Foundation Division of Ocean Sciences on September 15, 2021 to complete the project by August 31, 2024. The grant was awarded under the NSF's Geosciences program (CFDA 47.050), which supports basic research to strengthen understanding of the integrated Earth system. Specifically, the grant will fund collaborative research to elucidate brine-dominated, segment-scale hydrothermal discharge along...
- The National Science Foundation Division of Earth Sciences awarded the University of Washington $410,900 on August 1, 2026, through the Geosciences program (CFDA 47.050) to investigate the structure and properties of the Cascadia plate interface by analyzing exhumed paleo-megathrust fault systems in the Olympic Mountains of Washington State. The research team will examine fossil fault rocks to characterize the signature of earthquake processes and map fault geometry in detail, focusing on...
- 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...
- This two-year Project Grant award of $401,300 from the National Science Foundation Division of Ocean Sciences supports collaborative research on constraints of interseismic locking near the trench on the Oregon segment of the Cascadia Subduction Zone using seafloor geodesy. The research will be conducted through the Scripps Institution of Oceanography at the University of California San Diego under the NSF's Geosciences program (CFDA 47.050). This program supports basic research in the...
- The National Science Foundation Division of Earth Sciences awarded Massachusetts Institute of Technology $220,796 on August 1, 2026, under the Geosciences program (CFDA 47.050) to conduct laboratory experiments simulating deformation in subduction zones and connecting material failure to seismic signals. The recipient will conduct experimental work that mixes brittle and ductile materials to model subduction-zone deformation, recording acoustic emissions when material breaks during controlled...
- This two-year, $389,704 National Science Foundation project grant will support the development of a reference model describing the shear-wave velocity structure of oceanic crust and upper mantle for crustal ages of 0 to 9 million years. Funded through NSF's Geosciences program (CFDA 47.050), Woods Hole Oceanographic Institution will leverage 2012 ocean bottom seismometer data collected across the Juan de Fuca tectonic plate to constrain shear-wave velocities through advanced seismic modeling and...
- The National Science Foundation (NSF) awarded a Project Grant of $158,159 to the University of Hawaii at Manoa on January 15, 2024 through its Integrative Activities (CFDA 47.083) program. The grant will fund a collaborative research project to investigate the relationship between the structure of the Alaska-Aleutian subduction zone and megathrust earthquake characteristics. The project will utilize seismic data from community experiments to develop high-resolution models of the plate interface,...
- The National Science Foundation Division of Earth Sciences awarded Michigan State University $187,925 on January 1, 2027, under the Geosciences program (CFDA 47.050) to conduct collaborative research on seismic phenomena in the Eastern Aleutian Subduction Zone. The award, classified as a Project Grant, runs through December 31, 2030, with place of performance in East Lansing, Michigan. The project will deploy broadband ocean bottom seismographs in the Eastern Aleutian Subduction Zone to...
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, Cascadia, and Chile before expanding globally. The work will generate a global database of fracture zone and seamount locations on subducted slabs and analyze how bathymetric and tectonic features on oceanic plates control water pathways into the Earth's interior—a factor central to earthquake nucleation and hazard assessment. Results will inform next-generation seismic hazard assessment for the U.S. and support training of earthquake scientists. Performance occurs at Woods Hole, Falmouth, Massachusetts, with completion targeted for August 31, 2029. The assistance type is Project Grant.
