The 2025 Puerto Rico and Virgin Islands U.S. National Seismic Hazard Model Update: Ground Motion Model Selection and Comparison

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We evaluate, select, and describe the ground‐motion models (GMMs) used in the 2025 update of the U.S. National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). We identify the most appropriate models that align with GMM selection criteria for use in the PRVI region to improve the accuracy of seismic hazard assessments ...

Evaluation of Earthquake‐Induced Slope Displacements in Greater Vancouver Based on Probabilistic Framework and Using NBCC 2020 and EqDisp Code Platform

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Engineers frequently use simplified seismic slope displacement procedures to evaluate the performance of earth structures and natural slopes. Current practices typically adopt Newmark‐type and semi‐empirical seismic displacement prediction models (SDPMs) to estimate the seismic slope displacements (D) based on ground motion intensity measures at a ...

Empirical Scaling Relationships Between Fault Length and Throw‐Rates Modulated by Fault Interactions in Extensional Regimes

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Throw rates of active faults are expected to scale with fault length because the geometric moment of a fault is directly related to its dimensions. However, empirical data sets commonly display substantial scatter, which limits the use of fault scaling relationships for seismic hazard assessment and for understanding the mechanics of ...

Spatial and Temporal Variations in Slip Rate Over Millions of Years on an Extensional Fault System and Implications for Seismic Hazard

Tectonics, Volume 45, Issue 5, May 2026.
Abstract Slip rate is a key input for fault‐based seismic hazard assessment, with temporal and spatial variations in slip rate along and between faults influencing earthquake size and recurrence. Temporal variations in slip rate have been attributed to earthquake clustering and anti‐clustering in tectonically active settings.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Time‐ and State‐Dependent Damage Accumulation Due to Aftershocks Under an M9.0 Megathrust Earthquake in the Cascadia Subduction Zone

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1157-1175, 25 April 2026.
ABSTRACT This study develops a comprehensive framework for assessing time and state‐dependent aftershock damage accumulation under an M9.0 megathrust interface earthquake in the Cascadia Subduction Zone (CSZ). The framework integrates aftershock probabilistic seismic hazard analysis (APSHA) and state‐dependent fragility analysis (SDFA) within a ...

A Probabilistic Seismic Hazard Analysis Method Incorporating Physics-Based Simulation and Ground Motion Prediction Equation

International Journal of Disaster Risk Science
The traditional approach to probabilistic seismic hazard analysis (PSHA) relies on ground motion records, which restricts its application in regions with sparse seismic records or low seismicity.

The Main Factors Controlling Probabilistic Seismic Hazard Variability Due to Epistemic Uncertainty in Greece: Results from a One-Factor-at-a-Time Analysis

The Seismic Record
We present a one-factor-at-a-time (OFAT) sensitivity study for the Probabilistic Seismic Hazard Assessment (PSHA) in Greece. The analysis examines several PSHA controlling factors, such as seismic source model (geometry, etc.), active tectonics (faulting
