Bayesian Modeling of Crustal Azimuthal Anisotropy Supports Partial Crust–Mantle Anisotropic Decoupling in a Continental Back‐Arc, Northeast China

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract How crustal deformation responds to complex mantle flow in continental back‐arc settings remains poorly constrained. Here, we develop a Bayesian working‐likelihood approach to estimate crust‐averaged azimuthal anisotropy from P‐wave receiver functions. The method separates crust‐averaged velocity anisotropy from dip‐related apparent anisotropy

Estimating Arias Intensity From Response Spectrum

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2169-2183, August 2026.
ABSTRACT Arias intensity serves as a crucial metric to measure ground motion energy and is extensively utilized in earthquake engineering to analyze structural damage, slope instability, and the potential for soil liquefaction. Nevertheless, in many practical design scenarios, only the response spectrum is available, without corresponding information ...

Full‐scale Shaking Table Tests on a 10‐story Steel Moment‐resisting Frame Building with Buckling‐restrained Braces

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2356-2378, August 2026.
ABSTRACT In February 2023, a comprehensive series of shaking table tests were conducted at the E‐Defense facility, the world's largest three‐dimensional earthquake simulator, on a full‐scale 10‐story steel moment‐resisting frame supplemented with BRBs.

Comparison of Seismic Performance Assessment Using Observed or Simulated Ground Motions in Seismic Hazard Analysis and Ground Motion Selection

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2449-2465, August 2026.
ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

Evaluating the U.S. Geological Survey's Earthquake Shaking Hazard Forecasts and Their Implications on Seismic Risk

Earthquake Spectra, Volume 42, Issue 3, August 2026.
We analyze the last six update cycles of the long‐term probabilistic earthquake shaking hazard forecast from the U.S. Geological Survey (USGS) and discuss the changes in hazard estimates from the 1996 to the latest 2023 update of the National Seismic Hazard Model (NSHM) for the conterminous United States.

Seismic Fragility and Vulnerability of Partially Grouted Flexural‐Controlled Reinforced Masonry Buildings in Colombia

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This paper presents the development of analytical fragility and vulnerability functions for flexure‐controlled partially grouted reinforced masonry (RM) buildings that are representative of Colombian urban areas, with the goal of enhancing national seismic risk assessments.

Assessments of Liquefaction Triggering and Manifestation at Three Case History Sites in Napier Based on 1931 Hawke's Bay, New Zealand, Earthquake

Earthquake Spectra, Volume 42, Issue 3, August 2026.
The 1931 Hawke's Bay earthquake (∼MS 7.8) stands as one of New Zealand's most devastating, causing widespread liquefaction and damage across the city of Napier. However, Napier remains underrepresented in liquefaction hazard studies as compared to other regions in the country.

Post‐Event Ground Motion Estimation using Graph Neural Networks

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Accurate ground motion (GM) estimates are essential for forensic analysis of structural damage following major earthquakes when direct recordings at the location(s) of interest are unavailable. Contemporary post‐event GM estimation methods often leverage nearby observations to constrain estimates of intensity measures (IMs); however, existing ...

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...
