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 ...

Earthquake Spectra, Volume 42, Issue 3, August 2026.With the recent increases in measured ground motion records for large earthquakes, most notably the 2023 M7.8 Pazarcik earthquake in Türkiye, the potential for pervasive high velocity fault rupture propagation over an extensive fault length has been observed.

The Purpose and Definition of the Minimum Magnitude Limit in PSHA Calculations [PDF]
Seismological Research Letters, 2017 ABSTRACT A lower limit of magnitude M min is routinely defined for integrations of earthquake scenarios in probabilistic seismic‐hazard analysis but there is widespread misunderstanding of the technical bases for determining the value of this parameter.

Quantifying Model Selection Uncertainty in Structural Analysis: Methodology and Application
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1828-1844, 25 July 2026.ABSTRACT With increasing focus on complex engineering systems under rare events, computational models are critical for predictions due to the scarcity or absence of data. However, selecting an appropriate model can be challenging. Using a single model without available test calibration could result in significant bias in performance predictions. A case

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1887-1904, 25 July 2026.ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1811-1827, 25 July 2026.ABSTRACT Multivariate ground motion models (GMMs) that capture the correlation between different intensity measures (IMs) are essential for seismic risk assessment. Conventional GMMs are often developed using a two‐stage approach, where separate univariate models with predefined functional forms are fitted first, and correlation is addressed in a ...

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

Rural Sociology, Volume 91, Issue 2, June 2026.ABSTRACT Over the past two decades as global alarm over disruptive climate change has grown, coalitions of high‐ranking government officials and prominent activists have launched campaigns to protect and restore greenhouse gas absorbing rain forests. The initial results from these campaigns have varied dramatically across racial and ethnic landholding ...
