- 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 Division of Ocean Sciences awarded the Board of Regents of Nevada System of Higher Education (operating as University of Nevada, Reno) $182,990 on September 1, 2026, to investigate fault slip associated with very large earthquakes, specifically the 2011 Tohoku-Oki earthquake. The award funds analysis of fault zone samples recovered from hundreds of meters below the seafloor at three core sites on the plate boundary fault, sites separated by 30 meters but...
- 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 (NSF) awarded a $500,000 Project Grant through its Office of International Science and Engineering program (CFDA 47.079) to the University of California Santa Cruz (UCSC) to facilitate a coordinated global effort to understand subduction zone geohazards. This 4-year award aims to: Develop an intellectual community to compare global subduction zone observations and cooperatively instrument critical regions to enable breakthroughs in understanding earthquakes,...
- 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 $175,416 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research at Cornell University from August 2022 to July 2024. The university will investigate structure and seismicity within the southern region of the 1964 Great Alaska earthquake rupture zone using data from a dense array of seismic sensors deployed in Kodiak Island, Alaska. Researchers will reanalyze 2019 data from 400 instruments to identify small earthquakes and precisely locate...
- The National Science Foundation Division of Earth Sciences awarded the University of California Santa Cruz $406,808 on March 1, 2027, under the Geosciences program (CFDA 47.050) to conduct friction experiments on clay-rich materials from the Cascadia subduction zone under in situ pressure-temperature-fluid chemistry conditions. The research pairs laboratory friction testing using Ocean Drilling Program core samples with numerical quasidynamic earthquake cycle models to evaluate long-term...
- The National Science Foundation Division of Earth Sciences awarded Iowa State University of Science and Technology $402,989 on August 1, 2026, under the Geosciences program (CFDA 47.050) to conduct laboratory experiments simulating deformation in subduction zones. The research will combine brittle and ductile materials in controlled experiments to replicate the conditions where tectonic plates move beneath one another, recording acoustic emissions when material fractures during deformation. By...
- This $518,605 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund collaborative research to quantify strain and fluid flow along subduction interfaces. Penn State University will lead efforts to characterize chemical and mechanical processes controlling the healing of subduction zones between large earthquakes. Researchers will study ancient subduction exposures in Japan and Alaska spanning depths of 8-20 km and temperatures of 150-350°C. Electron...
The National Science Foundation Office of Integrative Activities awarded Cornell University $504,577 on September 1, 2026, under the Geosciences program (CFDA 47.050) to monitor fault zone fluid flow and earthquake hazards using subseafloor observatories in the Japan Trench subduction zone. The research analyzes data from borehole observatories installed at International Ocean Discovery Program Site C0019 during NSF-supported IODP Expedition 405 in 2024. Dense temperature sensor strings deployed in boreholes C0019D and C0019Q cross the shallow plate-boundary fault and span the overriding prism, with records recovered in subsequent expeditions. The project tests whether fluid flows primarily within the damage zone near the plate boundary, along branching faults, or within the subducting tectonic plate. Understanding how pore and fracture water pressure and rock permeability influence shallow fault slip will enhance understanding of earthquake and tsunami hazards in the region of the 2011 Tohoku-Oki earthquake. The award supports a postdoctoral researcher and undergraduate researchers. The project will produce open data and reusable analysis tools applicable to fluid flow study in other settings and will develop a comic book for public engagement on borehole observatory measurement techniques. Work is performed in Ithaca, New York with a period of performance from September 1, 2026, through August 31, 2029.
