Nonstationary Spatial Correlation of Earthquake Ground Motions in California

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Assessing seismic risk to spatially distributed infrastructure systems requires realistic representations of spatially correlated ground motions. Existing models for the spatial correlations of ground motions rely on strong second‐order stationarity assumptions, under which the correlation structure is assumed to be invariant across space, potentially ...

Development of Full‐Scale Experiment‐Based Seismic Fragility Functions for Code‐Compliant Fire Sprinkler Piping Systems

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Fire sprinkler systems are critical for fire safety, but their functionality can be impaired by seismic damage. This study develops new seismic fragility functions for acceleration‐sensitive damage requiring monitoring, maintenance, and repair in code‐compliant fire sprinkler piping systems, using experimental data from full‐scale experimental tests ...

Quantification of Direct Benefits of Functional Recovery‐Based Design for Seismic Resilience

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Lessons from recent major earthquakes have shown that current life‐safety‐centered seismic design practice falls short in ensuring a desirable post‐hazard recovery. Extensive economic losses, high demolition rates, and long recovery have signified a gap between design targets and society's expectations of seismic performance of code‐compliant buildings.

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 ...
