Opportunities for the U.S. Geological Survey's National Seismic Hazard Model to Improve Seismic Risk Assessment of Critical Infrastructure

Earthquake Spectra, Volume 42, Issue 2, May 2026.
As fragility and risk modeling techniques and computational capabilities evolve, complemented by moving toward more routine and systematic seismic risk assessment of all buildings and critical infrastructure, the authors pose a few critical questions to investigate how the U.S. Geological Survey (USGS) National Seismic Hazard Models (NSHMs) can be used

Seismic Hazard Assessment in Maluku Province Using PSHA

, 2023
On 10 January 2023, a strong earthquake with a moment magnitude (Mw) of 7.5 occurred in Banda Sea, Maluku Province. This earthquake caused casualties around the epicentre due to the building collapse which was not an earthquake-resistant structure.

2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

Earthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

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.
