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 ...

Jeoloji, arazi ve doygunluğu dikkate alan yeni Vs30 tahmin stratejisi: Türkiye uygulamasi

, 2022
Various parameters are used for geotechnical characterization of site conditions. Among them, most widely used one is average shear wave velocity in upper 30 meters (Vs30). So far, many different proxy-based approaches are proposed to predict Vs30 across

Constitutive expression of the active fragment of human vasostatin Vs30 in Pichia pastoris SMD1168H [PDF]

, 2018
"Vasostatin 30 (Vs30) is an active fragment derived from the N-terminal region (135–164 aa) of human calreticulin and has the ability to inhibit angiogenesis.

Development of Liquefaction‐Targeted Design Basis in U.S. Seismic Provisions

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Seismic design criteria for new buildings in the United States have historically focused on life safety performance objectives through minimizing the potential for structural collapse. Development of design criteria to meet this performance objective has evolved over time, leading to the current, risk‐targeted maximum considered earthquake (MCER ...

A Novel VS30 Prediction Strategy Taking Fluid Saturation into Account and a New VS30 Model of Türkiye

The averaged shear-wave velocity of the top 30 m (VS30) is widely used in earthquake engineering as a proxy to represent site responses. However, the spatial availability of measured VS30 is rather limited, and, so far, a region-specific VS30 model that ...

Application of Methods to Characterize VS30 in Alabama [PDF]

, 2022
One of the most important characteristics of a soil that is a basis for seismic analysis, is shear wave velocity (VS). VS has proved to be a valuable tool for site response analysis for seismic design since it has the potential to significantly affect ...

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 ...

Shaking‐Induced Small Seismic Velocity Changes as Revealed From Seismic Interferometry Analysis of Distributed Acoustic Sensing Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Understanding the spatio‐temporal variations in the physical properties of the Earth's crust is crucial for comprehending the dynamic processes linked to earthquakes. Conventional seismometer‐based analyses have limitations in spatio‐temporal resolution due to the sparse station distribution.

Investigation of Subsurface Characteristics by using a Vs30 Parameter and a Combination of the Hvsr and Spac Methods for Microtremor Arrays

International Journal of Technology, 2017
Palu City is an active seismic area in Indonesia due to the very active Palu-Koro fault system. The development of the city area, therefore, must consider the risks induced by the seismic activities. The risk assessment has to be supported by information
