Regional characterization of vs30 with hybrid geotechnical and geological data
Underground Space, 2023 Regional characterization of soil properties requires not only geostatistical models considering the spatial variability of soil properties but also methods that account for various sources of heterogeneous information.

Assessment of a Fast Proxy of Vs30 (Vs30m)
Sustainability, 2022 The most frequent parameter used to quantify seismic site response in ground motion models is time-averaged shear wave velocity in the top 30 m of a site (Vs30), used by many engineering design codes and most recently by published empirical-scaling equations to estimate the amplitudes of strong ground motion.

Methodology and Assessment of Proxy-Based Vs30 Estimation in Sichuan Province, China
International Journal of Disaster Risk Science, 2020 Although time-averaged shear wave velocity to the depth of 30 m (Vs30) is an important indicator of earthquake site effects, it is difficult to obtain.

Dual-proxy estimation of Vs30: the case study of the Marche Region (central Italy)
Journal of MapsThis study focuses on generating a shear-wave velocity averaged within the uppermost 30 m of the ground surface (Vs30) map for the Marche region (central Italy) using two commonly acknowledged proxies: topographic slope and lithological classification ...

STUDY ON SITE CONDITIONS BASED ON TOPOGRAPHIC SLOPE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 The travel-time averaged shear-wave velocity to a depth of 30m (Vs30) below the Earth’s surface is widely used to classify sites in many building codes. Vs30 is also used to estimate site classification in recent ground-motion prediction equations (GMPEs)
