Why do the largest continental earthquakes nucleate on branch faults?
POSTED ON SEPTEMBER 24, 2024 BY TEMBLOR
New research suggests branch faults serve as on-ramps to major fault superhighways. The key to this phenomenon might be that the branch fault ruptures faster than seismic waves can travel — the equivalent of breaking the sound barrier in Earth’s crust — delivering a strong kick to the major fault.
