Constraining the role of fault spacing in event synchronization

Funding: Caltech OK Earl Postdoctoral Fellowship Project description: Paleoseismic evidence from fault systems across the world suggests that fault synchronization and event clustering are ubiquitous behaviors in the geologic record. How does the spacing between neighboring faults influence event timing and synchronization across a fault system? We run a suite of models on two parallel strike-slip faults with identical rate and state friction parameters using simulator Quake-DFN. We vary the spacing between the two faults from 100 m to 20 km and examine the resulting earthquake sequences. Presentations: Poster presentation at the 2024 GMG Spring Meeting |
