Vertical Shear-Wave Velocity Profiles Generated from Spectral Analysis of Surface Waves: Field Examples

Liquefaction Hazard assessment using Horizontal-to-Vertical Spectral Ratio of Microtremor

In this paper, the spectral ratio of mmicrotremor, HSVR, is presented for estimating the liquefaction potential of layered soil in the coastal area of the Persian Gulf, which consists of a hard sandstone layer situated between two saturated sandy layers. The surface layer is thin, with a thickness between 2 and 5 meters. The purpose of this paper is to identify the relation between the liquefac...

a revised spatial autocorrelation method to study shear wave velocity

recordings of ambient noise or microtremors are increasingly used to find valuable information on soil in one dimension at a given site. ambient vibrations, which are assumed to be mainly composed of surface waves, can be used to determine the surface wave dispersion curve in order to retrieve shear wave velocity profile. in this regard, microtremors are usually recorded simultaneously in an ar...

Vertical shear plus horizontal stretching as a route to mixing

The combined effect of vertical shear and horizontal stretching leads to thin, sloping structures in tracer fields, whose vertical length scale is much smaller than their horizontal length scale. These structures are then vulnerable to vertical mixing processes. This effect needs to be taken into account when interpreting the horizontal structure of oceanic (and atmospheric) tracers and may exp...

Site classification using horizontal-to-vertical response spectral ratios and its impact when deriving empirical ground- motion prediction equations

We classify sites based on their predominant period computed using average horizontal-tovertical (H/V) response spectral ratios and examine the impact of this classification scheme on empirical ground-motion models. One advantage of this classification is that deep geological profiles and high shear-wave velocities are mapped to the resonance frequency of the site. We apply this classification ...
