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

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.

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.

Rare Synchronization Among Recurring Earthquakes
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Earthquakes are notoriously irregular, yet occasionally neighboring faults rupture in close succession, repeatedly, as if synchronized. Over successive cycles, differences in recurrence intervals, overall irregularity and external stressors should all drive neighboring faults out of phase.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Water plays a critical role in Earth's mantle dynamics and evolution, yet lower‐mantle storage mechanisms remain debated. δ‐AlOOH and SiO2 phases have been independently proposed as high‐pressure water hosts. Here, we conducted in situ synchrotron X‐ray diffraction experiments with a multi‐anvil apparatus and sintered diamond anvils to ...
