- 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 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...
- This two-year Project Grant from the National Science Foundation's Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $167,774 to the University of Houston to investigate mantle dynamics in the Pacific Northwest through 3D anisotropic seismic velocity modeling. The University will use surface wave tomography to construct a high-resolution model of seismic anisotropy in the region, revealing detailed mantle processes and testing mechanisms for geophysical...
- This Project Grant award for $398,707 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project between the University of Oregon and other institutions to study the geologic history and tectonic evolution of the Pacific Northwest region. The project aims to test models for the surface response to the Eocene collision of the Siletz oceanic terrane with western North America, as well as the subsequent post-collision adjustments that shaped...
- The National Science Foundation (CFDA 47.050 Geosciences) awarded a $348,474 project grant to Northwestern University to investigate the mechanics that govern the onset and recurrence of supershear earthquakes. This research aims to improve earthquake hazard models and support safer infrastructure design in earthquake-prone regions. The project combines theoretical modeling and numerical simulations to advance the understanding of supershear earthquake dynamics, focusing on long, mature...
- This $729,600 Project Grant was awarded on July 1, 2025 by the National Science Foundation's (NSF) Division of Earth Sciences under CFDA Program 47.050 - Geosciences. The grant will fund a research project led by the University of Oklahoma (OU) to advance methods for inferring and modeling megathrust faulting processes across timescales, from seconds to centuries, in three major subduction zones (Chile, Japan, and Alaska). The project aims to better understand megathrust systems and assess...
- This $238,875 Project Grant was awarded by the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) to the University of Utah. The grant aims to develop a detailed 3D model of the Los Angeles (LA) Basin, which is critical for accurately estimating earthquake ground motion and assessing seismic hazard in this densely populated area. The researchers will analyze data from a temporary 300-node geophone array deployed across the LA Basin in 2022, and combine it with other seismic...
This $248,297 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will fund collaborative research to improve understanding of how local geological structures affect earthquake ground motion amplification in the Pacific Northwest. The research team from Purdue University will develop new ways to constrain the subsurface structure of Cascadia forearc basins, which will provide better information to guide estimates of ground motions from seismic hazards in this densely populated region. The researchers will use passive seismic techniques, including particle motion analysis and horizontal-to-vertical spectral ratios, to characterize the shallow shear-wave velocity structure and basin geometry. All data, methods, and results will be openly shared to support the broader scientific community and regional velocity model-building efforts. This work aims to enhance scientific knowledge and improve earthquake hazard assessment and mitigation strategies in the Pacific Northwest.
