The National Science Foundation (NSF) Geosciences Program (CFDA 47.050) awarded a $399,601 project grant to the University of California Santa Cruz (UCSC) to conduct a series of laboratory experiments that directly measure fault rupture dynamics and associated seismic signals. The primary objectives are to:
- Assess magnitude predictability and the effect of fault barriers on the likelihood of large earthquake events.
- Examine the relationship between rupture velocity and final rupture size as observed through seismic data.
- Evaluate the scaled radiated energy of laboratory earthquakes and its implications for interpreting natural seismic observations and fault asperity distributions.
The project leverages UCSC's expertise and specialized laboratory equipment to provide new insights into fundamental earthquake source parameters and improve interpretation of seismological data. The research will foster international collaboration with scientists studying analogous high-risk fault systems, such as the Dead Sea Fault and San Andreas Fault. The award period runs from August 1, 2024 to July 31, 2027.
