Earthquake Ground Motion Cycle Count Datasets

Earthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents a comprehensive set of earthquake ground motion cycle count datasets derived from the NGA‐West2 and NGA‐Sub databases. We applied peak counting, mean‐crossing, level‐crossing, and rainflow cycle counting methods to over 275,000 acceleration time series.

CyberShake NZ: Probabilistic Seismic Hazard Analysis in New Zealand Using Physics‐Based Ground‐Motion Simulations

Earthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents the computational components and workflow developed to conduct probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) using physics‐based ground‐motion simulations, referred to as “CyberShake NZ.” Semi‐automated procedures generate multiple realizations of kinematic rupture models, create rupture‐specific velocity models ...

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

Earthquake 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.

Revisions to the 2023 U.S. 50‐State National Seismic Hazard Model

Earthquake Spectra, Volume 42, Issue 4, November 2026.
We present an update to the 2023 U.S. 50‐state National Seismic Hazard Model, based on questions and comments received from a range of users, as well as additional internal and building code reviews since its initial release. For the conterminous United States, the update includes (1) revised weighting of ground motion models in the Intermountain West,

Selection of Ground Motions for Hazard‐Consistent Incremental Dynamic Analysis Using Genetic Algorithms

Earthquake Spectra, Volume 42, Issue 4, November 2026.
Hazard‐consistent incremental dynamic analysis (HC‐IDA) provides a computationally efficient alternative to multiple stripe analysis (MSA) by using multivariate regression to account for the effects of spectral shape and duration on structural collapse capacity.

Tectonics on Early Earth Driven by Earth's Changing Shape During Tidal Recession of the Moon

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Few fragments of Earth's earliest crust have survived, and so this formative period of our planet's history is shrouded in mystery. To leverage the limited data available, it is important to understand all the processes that could have shaped our young planet.

On the Differential Conditioning of Sub‐Antarctic Mode Water and Antarctic Intermediate Water Over Decadal Time Scales

Journal of Geophysical Research: Oceans, Volume 131, Issue 11, November 2026.
Abstract We report results from a meridional transect performed along 150°W, 30°S to 60°S in the Southern Ocean (SO). This study aimed to document the rates of conditioning of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW), which are formed during deep mixing events in the austral winter.

Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

A New Amphibious Earthquake Catalog for the Alaska Peninsula: Training, Testing, and Applying Machine Learning Earthquake Picking in Offshore and Amphibious Environments

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract The dual seismological developments of large‐scale offshore observational networks and high‐quality machine‐learning earthquake detection and picking allow unprecedented seismicity detection in high hazard subduction zones. We develop a high resolution machine learning enhanced seismicity catalog for the Alaska Peninsula stretch of the Alaska ...
