Cornell University was awarded a $318,917 Project Grant from the National Science Foundation Division of Earth Sciences to conduct collaborative research on seismic cycles and earthquake nucleation on heterogeneous faults. Through laboratory experiments, numerical simulations, and analysis of data from Whillans Ice Stream in Antarctica, the researchers aim to better understand slow slip and microearthquakes that precede large earthquakes. The experiments will test how non-uniform fault properties like roughness, bends, and composition influence earthquake initiation. Computer models developed from the lab data will be tested against field observations from Antarctica to extend results to natural earthquake conditions and scales. Three graduate students and two undergraduates will receive training in earthquake science. This award supports the National Science Foundation's Geosciences program (CFDA 47.050) to advance fundamental understanding of integrated Earth system processes through basic research in atmospheric, earth, and ocean sciences. The completion date is April 30, 2026.
