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.

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 ...

Development of Liquefaction‐Targeted Design Basis in U.S. Seismic Provisions

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Seismic design criteria for new buildings in the United States have historically focused on life safety performance objectives through minimizing the potential for structural collapse. Development of design criteria to meet this performance objective has evolved over time, leading to the current, risk‐targeted maximum considered earthquake (MCER ...

Prediction of Soil Liquefaction Triggering Using Rule-Based Interpretable Machine Learning

Geosciences
Seismic events remain a significant threat, causing loss of life and extensive damage in vulnerable regions. Soil liquefaction, a complex phenomenon where soil particles lose confinement, poses a substantial risk.

Probabilistic Hazard Assessment of Coseismic Elastic Surface Deformation for the Leech River Valley–Devil's Mountain Fault System Using Stochastic Source Modeling

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study investigates the effect of incorporating the Devil's Mountain Fault (DMF) and its interaction with the Leech River Valley Fault (LRVF) on the elastic surface deformation hazard in and near the city of Victoria, British Columbia, Canada. Previously, the surface deformation hazard of the region has been characterized by considering the LRVF ...

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 12, Page 4893-4912, 25 August 2026.
ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of
