This Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $297,681 to Purdue University to better understand the relationship between orogenesis and seismogenesis along the southern Cascadia forearc region in northern California. The research team will analyze a recently acquired dataset using seismic methodologies including receiver function imaging, ambient noise interferometry, and joint inversion of receiver...

This $102,704 federal Project Grant award from the U.S. Geological Survey's Earthquake Hazards Program (CFDA 15.807) to the University of Alaska Fairbanks will optimize small seismic arrays for use in the ShakeAlert earthquake early warning system. The key activities include: Analyzing existing large earthquake P-wave data to determine frequency and noise characteristics to inform theoretical array sensitivity analyses. Deploying approximately two dozen seismic sensors near Kodiak, Alaska to...

This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award of $224,382 provides funding to the California Institute of Technology (Caltech) to develop a detailed 3D model of the Los Angeles Basin. The project aims to analyze seismic data from a dense 300-node geophone array deployed across the basin in 2022, combined with other seismic and gravity observations, to better understand the basin's complex tectonic structure and how it affects earthquake ground...

This federal Cooperative Agreement award, provided by the United States Geological Survey (USGS) under the Earthquake Hazards Program Assistance (CFDA 15.807), aims to improve the performance of the Finite Fault Rupture Detector (FINDER) algorithm within the ShakeAlert earthquake early warning system for the U.S. West Coast. The $150,430 award to the Swiss Federal Institute of Technology (Eidg. Technische Hochschule Zürich) will fund research activities focused on enhancing FINDER's capabilities...

This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) totaling $225,816 will support collaborative research to investigate the evolution of elastic wave properties during the seismic cycle. The primary objectives are to explore whether variations in seismic wave properties can be identified before and/or after earthquakes, determine the underlying physical mechanisms, and assess the potential for operational forecasting of ruptures on meter-scale...

This federal Cooperative Agreement award, provided by the United States Geological Survey (USGS) under the Earthquake Hazards Program Assistance (CFDA 15.807) program, supports the operation, maintenance, and improvement of the ShakeAlert earthquake early warning system for the U.S. West Coast. The $2,478,580 award, with a performance period from August 15, 2024 to August 14, 2027, will enable the California Institute of Technology (Caltech) and its collaborators at the University of...

This two-year, $151,076 Project Grant from the National Science Foundation's Geosciences program (CFDA #47.050) will support the development of a database of high-fidelity synthetic seismograms for incorporation into the Global Centroid-Moment-Tensor Project. The awardee, Princeton University, will work with the Princeton Numerical Seismology Group and Lamont-Doherty Earth Observatory to adapt the SPECFEM3D_GLOBE spectral element solver to generate synthetic seismograms across a global grid of...

This $191,710 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) is supporting a collaborative research effort to address fundamental issues linking great earthquakes with plate tectonics. The interdisciplinary team, led by the California Institute of Technology (Caltech), is developing advanced computational methods and algorithms to enable the simulation of long-term tectonic plate motions coupled with the space-time evolution of stresses...

This $110,662 federal Project Grant award, funded by the U.S. Geological Survey (USGS) under the Earthquake Hazards Program Assistance (CFDA 15.807), aims to develop a framework for continuously updating ground motion prediction equations. The proposed research by Virginia Polytechnic Institute & State University (Virginia Tech) involves collecting and processing seismic data to create physics-based and engineering-based ground motion models, leveraging a Bayesian regression approach to...
