Vs30 Mapping and Soil Classification in Tiznit Region Based On H/V Spectral Ration Method [PDF]

E3S Web of Conferences
The average shear wave velocity measured to a depth of 30 meters (VS30) is an important parameter for determining soil characteristics. As part of the seismic risk assessment in the Tiznit region, ambient noise recordings were made during the geophysical

Vs30 of Coastal Cities in Eastern Indonesia in the Context of Earthquake Phenomenology

Seismica
Shear wave velocity measurements to 30 m depth (Vs30) using Multichannel Analysis of Surface Waves (MASW) indicate high seismic risk to the built environment in coastal cities adjacent to the Sunda and Banda subduction zones in Eastern Indonesia.

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.

Dual-proxy estimation of Vs30: the case study of the Marche Region (central Italy)

Journal of Maps
This 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 ...

Soil Classification Mapping by Vs30 MASW Measurements in Gorontalo City

IOP Conference Series: Earth and Environmental Science
Abstract The city of Gorontalo, in the north of Sulawesi Island, has a relatively high potential for earthquake events. This condition is influenced by the meeting of three plates, namely the active subduction zone of the Sulawesi Sea trench, which is subducting to the south, and the Maluku Sea trench (Sangihe Trench), which is ...

Comparative analysis of Geotechnical and Geophysical Investigations for average shear wave velocity in Metro Manila

Energy Reports, 2023
Philippines is one of the most seismically active countries in Southeast Asia and records at least 20 earthquakes per day according to the PHIVOLCS. Vs30 is defined as the shear wave velocity of the upper 30-meter subsurface profile which is an important
