Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 14, Page 3714-3731, November 2026.
ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...

Influence of Site Amplification Approaches in PSRA: Insights From Five Different Cities

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
Regional and national seismic hazard models used in probabilistic seismic risk analysis often rely on generalized proxy‐based site terms to account for ground shaking amplification. This can result in coarse representations of site response, which can introduce bias or additional uncertainty in the associated risk results.

Suite of Regional Seismic Velocity Models for the U.S. Atlantic and Gulf Coastal Plains (CPVMv2.0): Incorporating Epistemic Uncertainty in Velocity Models

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
The U.S. Atlantic and Gulf Coastal Plain (CP) sediments are kilometers‐thick, low‐velocity deposits underlain by high‐velocity bedrock that create regional patterns of amplification and attenuation of ground motions. Capturing these effects is challenging because of the limited subsurface information available, particularly the shear wave velocity (VS)

Accounting for Biases in the Analysis of Building Damage Data for the 2023 M7.8 Türkiye/Syria Earthquake Sequence

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
In the aftermath of a large earthquake, several practical constraints affect the systematic collection of data for assessing building damage. The available data are therefore typically incomplete, frequently missing key information such as the type of construction, age and geographic location.

Collocated Geotechnical and Geophysical Test Dataset at Three Sites in Napier, New Zealand

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
Reliable assessment of liquefaction hazard, particularly in the context of groundwater fluctuations associated with hydroclimatic changes and variability between liquefaction assessment methods, necessitates supplementary data and advanced site characterization methods.
