Earthquake Spectra, Volume 42, Issue 3, August 2026.This study quantifies the influence of multidimensional effects on site response in the Wellington region of New Zealand by comparing results from different simulation approaches. Response‐spectral amplification functions from 1D and 2D site response analyses are compared to quantify the magnitude and spatial distribution of multidimensional effects ...

Seismic wave attenuation in the crust
Journal of Geophysical Research, 1964 Attenuation of seismic waves has been measured for many years. However, it is only recently that sufficient precision has been achieved and analytical techniques have been evolved which make possible the inversion of the experimental data [Anderson and Archambeau, 1964; Anderson and Kovach, 1964; Knopoff, 1964].

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 ...

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 ...

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.

Partitioning Site Amplification and κ0 in Earthquake Recordings
Earthquake Spectra, Volume 42, Issue 3, August 2026.This study explores site amplification and spectral decay (κ0) estimates, focusing on the challenge of separating the two in observed Fourier amplitude spectra (FAS). We apply two general approaches: a Bayesian broadband inversion for simultaneous estimation of site amplification and κ0, and slope‐based methods for direct κ0 estimation from the ...

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Enhancing the applicability of Gravity Recovery and Climate Experiment (GRACE) products poses challenges due to the trade‐off between the temporal and the spatial resolution within limits posed by the mission design. If a Kalman filter framework was adopted to characterize the relationship between monthly and finer temporal scales, it could ...

Spatial variation of coda wave attenuation in the Southern Indian Shield and its implications
Geologica Acta, 2012 During the recent past the Indian peninsular shield has experienced six damaging earthquakes of M 5.4-7.7 and compelled to readdress our understanding of the seismic attenuation characteristics for better evaluation of the seismic hazards in the so ...
