Contribution of HVSR measures for seismic microzonation studies [PDF]
Annals of Geophysics, 2018 The HVSR method applied to seismic noise can be a very useful technique to map the site effects of the territory, to identify the thickness of the soft covering and so the depth of the seismic bedrock. The case of the urban area of Oliveri is presented.

Compaction evolution observed via the HVSR of microtremors
Géotechnique Letters, 2013 The non-invasive measurement of horizontal to vertical spectral ratio (HVSR) of microtremors is proposed as a means to evaluate field compaction. The HVSR technique is a surface wave method that is quite distinct from the class of array-based surface wave techniques.

Statistical Analysis of Noise Horizontal-to-Vertical Spectral Ratios (HVSR)
Bulletin of the Seismological Society of America, 2005 Statistical properties of the horizontal to vertical spectral ratios (hvsr) applied to noise recording are analyzed in order to define optimal strategies for numerical processing and identification of possible artifacts. To this purpose, two time series have been analyzed: one constituted by environmental seismic noise in the presence of a genuine ...

Investigation of dynamically compacted ground by HVSR-based approach
Soil Dynamics and Earthquake Engineering, 2013 Abstract This paper proposes a HVSR (horizontal to vertical spectral ratio)-based approach to assess a deep and dynamically compacted fill area in Western Sydney. In addition to recognizing that the predominant resonance peak of the HVSR curve is a reflection of the impedance contrast between the surface layers and bedrock, the present paper ...

Detecting site resonant frequency using HVSR
, 2020 In this investigation, we examine the uncertainties using the horizontal-to-vertical spectral ratio (HVSR) technique on earthquake recordings to detect site resonant frequencies at 207 KiK-net sites. Our results show that the scenario dependence of response (pseudospectral acceleration) spectral ratio could bias the estimates of resonant frequencies ...

Non-stability of the noise HVSR at sites near or on topographic heights
Geophysical Journal International, 2020 SUMMARYThe horizontal to vertical spectral ratio (HVSR) of seismic noise is often used to investigate site effects, and it is usually assumed to be a stable feature of the site considered. Here we show that such an assumption is not always justified, and may lead to incorrect conclusions.

Teknik, 2013 Several methods for evaluating the effect of site specific condition of soil layers against earthquakes are presently available. Site Specific Analysis (SSA) and Horizontal-to-Vertical Spectral Ratio (HVSR) are two methods commonly used for estimating ...

Improvement of HVSR technique by cluster analysis
, 2013 The Horizontal to Vertical Spectral Ratio (HVSR) technique, applied to ambient noise, is widely used to quickly estimate the fundamental frequency of a site. The HVSR technique is based on numerous assumptions about the propagation medium and the nature of the seismic noise, often hard to verified.

From HVSR to site response function: potentiality and pitfalls
, 2022 The capability of the ambient vibration Horizontal to Vertical Spectral Ratios (HVSR) in capturing the main aspects of the seismic resonance phenomena was explored by numerical simulations. By considering a large set of Vs profiles, HVSR curves were simulated using two different models of the ambient vibration wavefield: the Diffuse Field Approach (DFA)
