- 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...
- This Project Grant award from the National Science Foundation Division of Ocean Sciences totals $137,255 to support the development of a plate-scale distributed strain sensing system as a candidate for earthquake early warning. Funded under the Geosciences program (CFDA 47.050), the University of California San Diego Scripps Institution of Oceanography will use the award period from October 1, 2022 to September 30, 2023 to establish the feasibility of measuring seafloor deformation along...
- This $249,924 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports the development of a long-lived, continuously operating seafloor geodesy reference station capable of operating in deep water. The grantee, Princeton University, will investigate using acoustic signals that only need to travel from the sea surface to the seafloor, removing the prior 3,000 meter depth limitation of existing seafloor geodesy techniques. This new approach involves...
- The National Science Foundation Office of Integrative Activities awarded the University of Texas at Austin $454,855 on January 1, 2027 under the Geosciences program (CFDA 47.050) to conduct integrated experimental and modeling research on subduction zone earthquake controls. The project will develop a system to distinguish whether shallow subduction faults build energy for infrequent large earthquakes and tsunamis or release stress through small events by measuring the rates of fault healing...
- 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 Division of Ocean Sciences awarded $186,758 to the University of Houston on August 1, 2026, to develop an autonomous uncrewed surface vehicle (USV) for seafloor geodetic surveys that will detect slow slip events and support subduction zone earthquake and tsunami research. The award funds development and testing of a faster, more cost-effective, and simpler-to-deploy vehicle capable of precise positioning via Global Navigation Satellite Systems–Acoustic (GNSS-A) technology, which combines satellite positioning with acoustic ranging to seafloor markers. The project targets detection of shallow slow slip events, which occur gradually over days to months where tectonic plates meet underwater and may trigger large earthquakes and tsunamis. Improved detection and understanding of these transient processes will inform earthquake and tsunami forecasting for natural hazard reduction. The work runs through July 31, 2029, and is performed in Houston, Texas. The project supports career development of an early-career investigator and participating graduate students, and leverages an institutional training program focused on industry-academia partnerships in technology development. This award is supported under the NSF Geosciences program (CFDA 47.050), which funds basic research to expand fundamental knowledge of the integrated Earth system.
