- The National Science Foundation Division of Earth Sciences awarded the University of Texas at Austin $320,400 on August 1, 2026, under the Geosciences program (CFDA 47.050) to investigate why earthquake foreshocks are rare in nature. The research uses meter-scale fault experiments with arrays of strain gauges and fault slip sensors to detect and measure nucleation zone expansion and couple its evolution to spatiotemporal changes in foreshocks. The project will quantify the coupling between...

- The National Science Foundation awarded a $174,000 Project Grant to Providence, Rhode Island for work investigating the competition between thermal pressurization and dilatancy on rough surfaces at earthquake slip rates. This funding supports a two-year research project under the Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the award will allow investigation...
- Federal Grant Award Summary The National Science Foundation's Division of Earth Sciences has awarded $345,000 through the Geosciences program (CFDA 47.050) to the University of California, Los Angeles for a Project Grant extending from August 15, 2025 through July 31, 2028. This research initiative will produce advanced seismic analysis methodologies and a comprehensive public database of rupture characteristics for global large earthquakes (magnitude 7.0 and greater) from 2000 to 2022. The...
- 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 Trustees of Boston University $210,687 on August 15, 2026, under the Geosciences program (CFDA 47.050) to develop new approaches to earthquake stress drop estimation and quantify variations in high-frequency seismic radiation. Work runs through July 31, 2029, at Boston University's location in Boston, Massachusetts. The project addresses inconsistencies in stress-drop measurements across different research groups by developing robust, systematic methods to analyze high-frequency radiation from earthquakes and provide error estimates. Relative stress-drop values among nearby earthquakes are more reliably resolved than absolute values, and this work will jointly perform analyses to improve understanding of stress release variations and their dependence on seismic magnitude, depth, time, and tectonic regime. Research focuses on California and New Zealand, both regions of high seismic activity, using data from national seismic station networks in both countries. The project will strengthen U.S.–New Zealand scientific collaboration and provide training for students and early-career researchers. Better stress-drop measurements and understanding of earthquake behavior variation support improved predictions of ground motion hazard during future earthquakes.
