- This two-year project grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $180,000 to Dr. James Neely to conduct research assessing whether small and large earthquakes release energy in the same manner. Dr. Neely will use computer simulations of synthetic earthquakes to examine assumptions about earthquake energy release and compare stress drop estimates from different commonly used methods to known stress drop values in simulated data. This will identify...
The National Science Foundation Office of Integrative Activities awarded $537,000 to the University of California San Diego's Scripps Institution of Oceanography on August 15, 2026, under the Geosciences program to develop new approaches to earthquake stress drop estimation and quantify variations in high-frequency seismic radiation. The research will improve systematic analysis of earthquake behavior by addressing inconsistencies in stress-drop measurements across scientific groups and constraining uncertainties in seismic attenuation and model parameterization. Work focuses on California and New Zealand, leveraging seismic station data from national networks in both countries. The project will establish more robust methodologies for resolving relative stress-drop values among nearby earthquakes and investigate how stress release during rupture varies by seismic magnitude, depth, time, and tectonic regime—factors critical for predicting ground motion variability and earthquake hazards. The research also aims to strengthen U.S.–New Zealand scientific collaboration and provide training for students and early-career researchers. Performance will occur in La Jolla, California through July 31, 2029.
