文摘
- •
Multi-millennial, multi-earthquake strain super-cycles occur on the Garlock fault.
- •
Super-cycles may coincide with temporal changes in elastic strain accumulation rate.
- •
Variable strain accumulation rates may be tied to temporally variable fault strength.
- •
Strain super cycle behavior precludes use of many probabilistic seismic hazard models.
- •
A deeper understanding of earthquake occurrence requires system-level analysis.
