Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with...

Efficient Physics-Informed Ground-Motion Simulations with Reduced-Order Models: CyberShake Implications and High-Resolution Site Terms for Southern San Andreas Fault Earthquakes

ABSTRACT Recent advances in Probabilistic Seismic Hazard Analysis (PSHA) leverage physics-based ground-motion simulations to estimate seismic hazard, such as the CyberShake project. However, computational costs quickly escalate when performing PSHA for numerous faults or sites an...
