- The National Science Foundation Office of Integrative Activities awarded the University of New Mexico $743,813 on September 1, 2026, under the Geosciences program (CFDA 47.050) to image the plate interface across the 1964 Alaska earthquake rupture zone and determine the causes for changes in slip behavior between locked and creeping sections of the megathrust. The project will acquire long-offset multichannel seismic reflection and wide-angle ocean bottom seismometer data spanning the entire...
- This National Science Foundation (NSF) Division of Earth Sciences Project Grant, awarded to the University of California Santa Cruz (UCSC), aims to advance the understanding of subduction fault and earthquake mechanics. Through a combination of new experiments on subduction zone rocks and numerical modeling, the project will investigate how the rheology (deformation behavior) of the megathrust fault zone, and the heterogeneity within it, affect fault slip behavior. Additionally, the project will...
- The National Science Foundation (NSF), through its Geosciences program (CFDA 47.050), awarded a $272,664 project grant to the University of Texas at Austin to conduct collaborative research on subduction megathrust rheology. The research aims to quantify how the deformation behavior and spatial heterogeneity of subduction zone rocks affect fault slip behavior, including the occurrence of slow earthquakes and slip events. The project will involve new laboratory experiments on subduction zone...
- The University of New Mexico received a $187,307 project grant award from the National Science Foundation Division of Earth Sciences to conduct research characterizing and quantifying carbon sequestration processes across the Andean convergent margin. The award period runs from January 1, 2022 through December 31, 2024. The research is being conducted under the Geosciences program (CFDA 47.050) of the NSF, which supports basic research to strengthen understanding of the integrated Earth...
- 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 Utah $210,713 on January 1, 2026, under the Geosciences program (CFDA 47.050) to conduct experimental research assessing the roles of wear and roughness on dynamic fault friction. The project will advance earthquake physics through controlled laboratory experiments using a specialized deformation apparatus to explore mechanisms regulating fault friction during seismic slip. The work includes experimental...
- 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 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...
The National Science Foundation Office of Integrative Activities awarded the University of New Mexico $376,555 on August 1, 2026, for a CAREER-track project grant to investigate megathrust frictional locking and stress accumulation in subduction zones. The research will develop a systematic, uniform atlas of kinematic coupling across globally distributed megathrusts and produce time-dependent models to capture how coupling and locking evolve in response to slow slip events and earthquakes. The work focuses on improving physics-based understanding of fault behavior in the shallow offshore portions of subduction zones, a region critical for forecasting large earthquakes and tsunamis that pose risks to coastal communities worldwide. The project will also advance understanding of systematic variations in megathrust kinematic and frictional properties on a global scale. An integrated educational component supports curriculum development, including one new course, a summer workshop for undergraduates, and an interactive online asynchronous course designed for broad accessibility to build computational skills for geoscientists. Performance runs from August 1, 2026, through July 31, 2031, with work performed at the University of New Mexico in Albuquerque, New Mexico. The award is funded under the NSF Geosciences program (CFDA 47.050).
