HVSR, Amplifications and ESAC: Some Clarifications

2020
This chapter discusses some points regarding two classical passive techniques more and more popular in seismic micro-zonation studies: the Horizontal-to-Vertical Spectral Ratio (HVSR) and the ESAC (Extended Spatial AutoCorrelation), a sort of “generalized” SPAC (SPatial AutoCorrelation).

Vulnerability Analysis of Andalas University Library Building Using Microtremor HVSR Method

Journal of the Physical Society of Indonesia
This research aims to analyze the vulnerability of the Andalas University Library UPT Building which is located in an earthquake-prone area using the microtremor HVSR method. Measurements were taken at 20 points on each floor of the building to determine

Mechanism of Turn-To-Turn Protection Maloperation and Anti-Maloperation Measure for HVSR

2025 5th Power System and Green Energy Conference (PSGEC)
When a high-voltage shunt reactor (HVSR) is applied in a long transmission line system equipped with series compensation devices, the non-periodic components generated during fault recovery may cause maloperation of the HVSR turn-to-turn Protection ...

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.

Horizontal-to-Vertical Spectral Ratio (HVSR) IRIS Station Toolbox

Seismological Research Letters, 2020
AbstractThe 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.

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 ...

HVSR Technique Improvement Using Redundant Wavelet Transform

2009
In this study we demonstrate the use of Wavelet Transform (WT) as all improvement tool for the horizontal to vertical spectral ratio (HVSR) technique. Since the use of non-stationary transients in microtremor signals remains an open question we investigate the effect of long duration undetectable (by amplitude thresholding methods) transients in HVSR ...

3D shear wave velocity imaging of the subsurface structure of granite rocks in the arid climate of Pan de Azúcar, Chile, revealed by Bayesian inversion of HVSR curves

Earth Surface Dynamics
. Seismic methods are emerging as efficient tools for imaging the subsurface to investigate the weathering zone. The structure of the weathering zone can be identified by differing shear wave velocities as various weathering processes will alter the ...
