- The National Science Foundation Division of Ocean Sciences awarded The Trustees of Columbia University in the City of New York $359,522 on September 1, 2026, under the Geosciences program to investigate fault slip associated with very large earthquakes using samples recovered from the Tohoku-Oki earthquake fault zone. The project analyzes three cores extracted hundreds of meters below the seafloor from the plate boundary fault zone, with sample sites only 30 meters apart but fault zone thickness...
- 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,...
- This Project Grant award from the National Science Foundation's (NSF) Geosciences program (CFDA 47.050) provides $347,238 to Michigan State University (MSU) to conduct collaborative research on the structure and behavior of the Alaska megathrust subduction zone. The project aims to enhance the fundamental understanding of how geological structures influence seismic activity in subduction zones, with the ultimate goal of improving earthquake hazard mitigation efforts. Key research activities...
- 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 (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 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 Trustees of Columbia University in the City of New York $118,653 on September 1, 2026, under the Geosciences program (CFDA 47.050) to image the plate interface across the 1964 Alaska earthquake rupture zone. The project will acquire long-offset multi-channel seismic reflection and wide-angle ocean bottom seismometer data spanning the entire rupture zone of the magnitude 9.2 1964 Alaska subduction zone earthquake—the largest recorded in United States history. The seismic profiles will image the incoming plate structure, upper plate fault geometries, megathrust reflection signature, and material properties near the trench within and across the rupture zone. The work will help determine why some sections of the rupture zone are currently locked and accumulating strain while other sections are creeping, and will test hypotheses about how along-strike variability in subduction inputs, the Yakutat/Pacific plate boundary, forearc structures, and near-trench pore-fluid pressures control variations in locking and coseismic slip behavior. Results will improve understanding of the processes generating great earthquakes with relevance to earthquake hazards in Alaska and other subduction zones worldwide. The project will provide at-sea training for graduate students from multiple institutions. Performance occurs in Palisades, Orangetown, New York. The period of performance runs from September 1, 2026, through August 31, 2028. The assistance type is a Project Grant.
