Abstract:
Abstract The horizontal-to-vertical spectral ratio (HVSR) for seismic ambient noise is a popular method that can be used to estimate the predominant frequency at a given site. In this article, we introduce the Incorporated Research Institutions for Seismology (IRIS) Data Management Center’s (DMC’s) openly available HVSR station toolbox. These tools offer a variety of ways to compute the spectral ratio by providing different averaging routines. The options range from the simple average of spectral ratios to the ratio of spectral averages. Computations take advantage of the available power spect

Abstract This study compares the HVSR technique (Horizontal to Vertical Spectral Ratio), based on seismic event records, and the HVSRN technique (Horizontal to Vertical Spectral Ratio of Noise) using seismic noise registrations. Both methods allow us to study the amplification phenomenon of a horizontal component of seismic waves when the waves reach loose sediments in subsurface layers. The seismic data were measured at a three-component single seismic station located in the village of Tarnówek, in the Legnica-Głogów Copper District. The results of the study demonstrate that average HVSRN and

Abstract:
The Horizontal-to-Vertical Spectral Ratio (HVSR) of ambient vibration measurements is a common tool to explore near surface shear wave velocity (Vs) structure. HVSR is often applied for earthquake risk assessments and civil engineering projects. Ambient vibration signal originates from the combination of a multitude of natural and man-made sources. Ambient vibration sources can be any ground motion inducing phenomena, e.g., ocean waves, wind, industrial activity or road traffic, where each source does not need to be strictly stationary even during short times. Typically, the Fast Fourier Trans

Abstract:
Horizontal to vertical spectral ratio (HVSR) based on seismic ground motion is an important index to study site conditions and dynamic characteristics (seismic effect). Due to the influence of the vertical dynamic amplification effect of the site, the Fourier spectral ratio calculated according to the surface motion and downhole motion is quite different from that of the horizontal and vertical ground motion in the case of strong vibration input. However, our recent research shows that when considering the time-varying characteristics of ground motion, the time-varying surface-downhole spectra

Abstract Frequency-dependent horizontal-to-vertical spectral ratios (HVSRs) of Fourier amplitudes from three-component recordings can provide useful information for site response modeling. However, such information is not incorporated into most ground-motion models, including those from Next-Generation Attenuation projects, which instead use the time-averaged shear-wave velocity (VS) in the upper 30 m of the site and sediment depth terms. To facilitate utilization of HVSR, we developed a publicly accessible relational database. This database is adapted from a similar repository for VS data and

Ambient noise measurements may be used under certain conditions to estimate characteristics of seismic response in a given site, namely the fundamental frequency and amplification at resonance. Both parameters depend on the geological structure and the dynamic properties of soils in the study area. The method known as Horizontal to Vertical Spectral Ratio technique, HVSR (Langston, 1979; Nakamura, 1989), provides a reliable estimate of the resonant frequency in most soil sites (Borcherdt, 1970), but the associated amplification is usually underestimated (Field &amp;amp; Jacob, 1995; Malagnini

Abstract:
Les vallées enfouies constituent un type d'aquifère important dans le paysage glaciaire du Canada. En raison de l'histoire complexe de l'érosion et du remplissage, il peut être difficile de définir la géométrie de la vallée et les caractéristiques des sédiments. Des transects sismiques de deux vallées enfouies précédemment identifiées ont été acquis en Ontario à l'Arboretum de l'Université de Guelph et dans un environnement périurbain au sud de la ville voisine d'Elora.
