HVSR fpeak-Based VS30 Estimation Model and Its Applicability to GMPE in Southwest China

Seismological Research Letters
We determined the first significant peak frequency (f0) and highest significant peak frequency (fpeak) from the horizontal-to-vertical spectral ratio curves for each strong motion station and proposed logarithmic bilinear models for VS30–f0 and VS30 ...

Development of a GIS-Based Predicted-VS30 Map of Türkiye Using Geological and Topographical Parameters: Case Study for the Region Affected by the 6 February 2023 Kahramanmaraş Earthquakes

Seismological Research Letters
The time-averaged shear-wave velocity in the upper 30 m of a site (VS30) is virtually essential in characterizing local soil conditions for multiple purposes, including estimation of site effects, anticipated ground-motion levels, seismic hazards, and ...

A 30 Arcsec Resolution VS30 Map for Mainland China Using Refined Topographic Slope-Based Cokriging (SCK) Model

Bulletin of The Seismological Society of America (BSSA)
In 2022, we proposed a VS30 proxy model based on the Cokriging method, integrating local VS30 measurements with topographic slope data (SCK model, Zhou et al., 2022). Utilizing this model, a VS30 map for mainland China was developed based on 7797 local

A global hybrid VS30 map with a topographic slope–based default and regional map insets

, 2020
Time-averaged shear wave velocity over the upper 30 m of the earth’s surface (VS30) is a key parameter for estimating ground motion amplification as both a predictive and a diagnostic tool for earthquake hazards.

Regional Arias Intensity Attenuation Relationship for Taiwan Considering VS30

Bulletin of the Seismological Society of America, 2012
The Arias intensity is a measure of earthquake intensity arrived at through the integration of a square of the acceleration time history. It has been demonstrated to be an effective predictor of earthquake damage potential in relation to short-period structures, liquefaction, and seismic slope stability, and has begun to be considered as a ground ...

Extending the Modified Square-Root-Impedance Method for the Development of Site Amplifications Consistent with the Full-Resonance Approach to a Range of VS30 Values

Bulletin of The Seismological Society of America (BSSA)
The square-root-impedance (SRI) method is commonly used to approximate the seismic site amplifications computed using the full-resonance (FR) method for gradient shear-wave velocity (VS) profiles that are smoothly varying with depth.

Microzonation models for Montreal with respect to Vs30

2015
The development of seismic microzonation maps is now a prerequisite for performing advanced seismic hazards and seismic risk assessments in urban areas. Current microzonation procedures are based on classifying site response in soil categories based on VS30. Inmany practical cases, information on shear wave velocity is sparse and analystsmust resort to
