Rapid Estimation of Vs30 Through Elitist Genetic Algorithm HVSR Inversion and Refraction Microtremor Data Analysis in the Greater Metro Manila Area and Leyte Province, Philippines

Applied Sciences
Vs30, the average shear wave velocity in the uppermost 30 m, is a critical parameter in seismic hazard analysis. In the Philippines, the Refraction Microtremor (ReMi) survey is the standard method for Vs30 Estimation.

EVALUATING LIQUEFACTION SUSCEPTIBILITY THROUGH HVSR AND MASW METHODS: A CASE STUDY IN MAMUJU, WEST SULAWESI, INDONESIA

Rudarsko-geološko-naftni Zbornik
The 2021 Mamuju earthquake (Mw 6.2) highlighted the region's high vulnerability to liquefaction due to its proximity to active tectonic zones, as well as the presence of Holocene alluvial deposits, unconsolidated sedimentary formations, and water ...

Vs30 Derived from Geology: An Attempt in the Province of Quebec, Canada

The influence of local site conditions is important when assessing the distribution of building damage and seismic risk. The average shear-wave velocity of the top 30 m of soil, Vs30, is one of the most commonly used parameters to characterize site ...

Estimating S-wave velocity profiles from horizontal-to-vertical spectral ratios based on deep learning

Soils and Foundations
S-wave velocity (Vs) profile or time averaged Vs to 30 m depth (VS30) is indispensable information to estimate the local site amplification of ground motion from earthquakes.

Multi-channel analysis of surface wave method for geotechnical site characterization in Yogyakarta, Indonesia

E3S Web of Conferences, 2019
On May 27th 2006, Yogyakarta earthquake happened with 6.3 Mw. It was causing widespread destruction and loss of life and property. The average shear wave velocity to 30 m (Vs30) is useful parameter for classifying sites to predict their potential to ...

Regional Correlations of VS30 and Velocities Averaged Over Depths Less Than and Greater Than 30 Meters

, 2011
International audienceUsing velocity profiles from sites in Japan, California, Turkey, and Europe, we find that the time-averaged shear-wave velocity to 30 m (VS30), used as a proxy for site amplification in recent ground-motion prediction equations ...
