Project Grant 2530225
- The National Science Foundation Division of Earth Sciences awarded the University of Washington $441,394 on September 1, 2026, to measure salt marsh geomorphic response to rapid sea-level rise using the 1700 Cascadia earthquake as a natural laboratory. The research will use stratigraphic analysis and age-dating of sediment cores from the Cascadia margin integrated with numerical modeling to quantify lag times between coseismic subsidence and salt marsh reestablishment of dynamic equilibrium with...
- The National Science Foundation (NSF) awarded a $261,123 Project Grant under the Geosciences program (CFDA 47.050) to the University of Oregon (UO) to conduct a comprehensive study of the Cascadia subduction zone, focusing on seismic and tsunami activity around the year 1700 CE. The key objectives are to: Map high-resolution paleotsunami deposits at two key locations along the Cascadia subduction zone, and Execute thousands of advanced tsunami inundation models to test hypotheses about...
- The University of Washington was awarded a $271,960 two-year Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050). The grant will support collaborative research to study constraints on interseismic locking near the trench on the Oregon segment of the Cascadia Subduction Zone using seafloor geodesy (GNSS-A). As the awardee, the University of Washington will leverage its expertise in ocean sciences and geosciences...
- This two-year, $354,309 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research to develop a new three-dimensional subsurface framework model of the Cascadia subduction zone in the Pacific Northwest. The awardee, the University of Texas at Austin, will analyze seismic data collected during the 2021 Cascadia Seismic Imaging Experiment to study the geometry of the plate interface along the margin, variations in plate interface properties, the...
- This two-year Project Grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), provides $100,459 to the University of Washington to support collaborative research building a new three-dimensional subsurface framework for the Cascadia Subduction Zone through integrated analysis of data from the 2021 Cascadia Seismic Imaging Experiment (CASIE21). Key products include a regional-scale structural interpretation of offshore Cascadia from...
- The National Science Foundation (NSF) awarded a $274,364 Project Grant to the University of North Carolina at Wilmington (UNCW) under its Geosciences program (CFDA 47.050). The objective of this 3-year award, commencing on May 1, 2024, is to conduct a comprehensive study of the Cascadia subduction zone, focusing on seismic and tsunami activity around the year 1700 CE. UNCW will carry out high-resolution mapping of paleotsunami deposits at two key locations along the Cascadia subduction zone...
- The National Science Foundation Division of Earth Sciences awarded the University of Washington $334,964 on September 1, 2026, under the Geosciences program to investigate deformation of Earth's rigid outer shell as it sinks into the mantle beneath the northern Andes using naturally deformed xenolith rocks. The project will determine the rheological properties of a lithospheric section below the North Andean Arc in southern Colombia by analyzing xenoliths brought to the surface by volcanic...
- This $174,000 two-year project grant from the National Science Foundation Division of Earth Sciences aims to advance understanding of episodic tremor and slip in subduction zones. Funded under the Geosciences program (CFDA 47.050), which supports basic research to strengthen knowledge of the integrated Earth system, this award will fund research into the role of metasomatic alteration in subduction zone seismic phenomena from September 2021 through August 2023. The grantee, located in Seattle,...
- This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $470,318 to the University of North Carolina at Chapel Hill from October 2021 through December 2022. The award will support collaborative research to better understand the contribution of crustal deformation to present-day tectonics at convergent margins like the southern Cascadia forearc. Researchers will utilize multiple geochronologic techniques to develop a record of exhumation and erosion in...
- The National Science Foundation Division of Earth Sciences awarded Purdue University $317,121 on August 15, 2026, under the Geosciences program (CFDA 47.050) to conduct multiscale seismic imaging analysis of the Cascadia volcanic arc. The project, a collaborative research initiative, will examine subsurface structures beneath nine of the eleven high-threat volcanoes in the Cascades to improve understanding of magma system variability, magma pathways, and reservoir locations across the volcanic...
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 testing a hypothesis that broader mélange fabrics formed through viscous interseismic processes while discrete localized fault strands formed brittlely during co-seismic slip. This work will clarify the properties governing elastic locking and earthquake strain release in sediment-rich subduction zones like the Cascadia megathrust, which poses major earthquake and tsunami hazards to the USA and Canada. The project includes graduate student training and regional outreach to enhance STEM education and public engagement. Performance runs through July 31, 2028, with work conducted in Seattle, Washington.
