“…Therefore, it is important to predict V s profiles in order to comprehend how seismic waves would travel through the subsurface. In areas with a high level of seismic activity, this information is essential for estimating the magnitude of ground vibrations and informing seismic design standards and building codes [129]. In order to customize rehabilitation procedures to specific soil conditions at various locations, Liu et al, in 2022 [130], emphasized the critical role of accurately predicting the V s , as it is essential for assessing infrastructure resilience and facilitating modifications and reinforcements of older structures to meet current seismic safety standards.…”

Shear wave velocity (Vs) is a critical parameter in geophysical investigations, micro-zonation research, and site classification. In instances where conducting direct tests at specific locations is challenging due to equipment unavailability, limited space, or initial instrumentation costs, it becomes essential to estimate Vs directly, using empirical correlations for effective site characterization. The present review paper explores the correlations of Vs with the standard penetration test (SPT) for geotechnical site characterization. Vs, a critical parameter in geotechnical and seismic engineering, is integral to a wide range of projects, including foundation design and seismic hazard assessment. The current paper provides a detailed analysis of the key findings, implications for geotechnical engineering practice, and future research needs in this area. It emphasizes the importance of site-specific calibration, the impact of geological background, depth-dependent behavior, data quality control, and the integration of Vs data with other geophysical methods. The review underlines the continuous monitoring of Vs values due to potential changes over time. Addressing these insights and gaps in research contributes to the accuracy and safety of geotechnical projects, particularly in seismic-prone regions.

“…Like others, the seismic hazard study is subject to some best engineering judgment, which includes the thresholds of earthquake magnitude and source-to-site distance for an earthquake that could possibly cause damage to modern structures. In this paper, the writers specifically used magnitude and distance thresholds as M w 5.5 and 200 km, respectively, similarly to those employed by several seismic hazard studies (e.g., Fernandez and Fatehi 2013;Wang et al 2012aWang et al , 2013.…”

“…The reasons of adopting the two models in this study are as follows: (1) they were developed with local earthquake data; (2) most areas in the Taipei Basin are soil sites; and (3) like most seismic hazard assessments (e.g., Cheng et al 2007;Fernandez and Fatehi 2013;Wang et al 2013), multiple models were adopted to account for the epistemic uncertainty, given the two local relationships are equally suitable for the study region and the analysis.…”

The region around Taiwan is known for high seismicity. Under the circumstances, seismic hazard assessments and proper earthquake-resistant designs are essential to the region. From a well-studied earthquake catalog, this paper presents the statistics of major earthquakes (i.e., moment magnitude M w ≥ 5.5 and distance ≤ 200 km) around the most important city in Taiwan (i.e., Taipei). The analysis shows that the mean annual rate of the major earthquakes is 2.79 around the city, with mean magnitude and SD equal to M w 6.12 and 0.68, respectively, and mean source-to-site distance and SD equal to 129 and 39 km, respectively. With the earthquake statistics and local ground motion models, a seismic hazard assessment was conducted with Monte Carlo simulations (MCSs). The analysis shows the mean rate for peak ground acceleration ≥ 0.23g (where g is gravitational acceleration) should be around 0.013 per year, indicating that the current design peak ground acceleration in Taipei. From this paper, the current seismic design in Taipei might not be as conservative as expected, and a review and revision could be needed for assuring the city's seismic safety against high seismicity in the region.
