- 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 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...
- This $393,670 National Science Foundation award under the Geosciences program (CFDA 47.050) funds research at the University of California, Davis from March 2022 through February 2025 to test the role of metastable olivine in subduction dynamics and deep earthquakes. The researchers will use state-of-the-art numerical simulations integrating experimental and observational parameters to model various subduction scenarios with and without the presence of metastable olivine. They will compare model...
- This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) supports a collaborative research project between the University of California, Santa Cruz (UCSC) and Hebrew University to directly measure fault rupture dynamics and seismic wave propagation in a laboratory setting. The $399,601 award, effective from August 1, 2024 to July 31, 2027, will leverage specialized laboratory equipment to conduct high-speed imaging and in-situ seismogram...
- 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 work includes experimental...
- The National Science Foundation awarded a two-year, $174,000 Project Grant to researchers at Riverside, California under the Geosciences program (CFDA 47.050). The grant will support work using distributed acoustic sensing to detect tremors and characterize earthquake hazard sites in the Cascadia region. Through June 2022 to May 2024, the grantees will evaluate earthquake risks by deploying fiber optic cables to monitor seismic activity. Insights gained from this work will further the...
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 earthquake behavior and recurrence intervals in the Cascadia region. Experimental work uses a triaxial apparatus at UCSC to measure how frictional strength and sliding stability of clay-rich subduction interface materials respond to fluid chemistry variation at elevated temperature and pressure. Microstructural imaging and elemental distribution analysis will characterize deformation related to physicochemical processes. The award period runs through February 28, 2029, with performance at the Santa Cruz, California campus. The project supports undergraduate research experiences in seismic hazard science and engages federal stakeholders through partnerships advancing geologic hazard resilience.
