3D Broadband Ground-Motion Simulations of Cascadia Megathrust Earthquakes: Full-Margin Scenarios Incorporating Variable Magnitudes and Frontal Thrust Splay Faulting

Great megathrust earthquakes (∼Mw 8–9) that rupture along the Cascadia Subduction Zone pose significant shaking and tsunami hazards to the U.S. Pacific Northwest. Although these large earthquakes are documented in the geologic record, none have been recorded with modern instrumentation, complicating regional seismic...

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression. Results show that neither viscoelastic relaxation nor afterslip alone fully expl...
