Intellectual Merit This project developed theoretical/computational and observational approaches to elucidate the physics of a recently discovered phenomenon: tectonic (non-volcanic) tremors. The new seismological observations focus on the Anza gap of the San Jacinto fault, one of the most seismically active faults in southern California. The models address the role of multi-scale fault heterogeneities on the broad spectrum of fault slip behavior.
Broader Impacts The project supported two graduate students and provided opportunity for an early career researcher (the PI) to develop mentorship skills. The results of this project contribute to our understanding of tremor, a phenomenon that might provide a natural creepmeter to monitor aseismic processes before large earthquakes.
