Improvement of HVSR technique by wavelet analysis

Soil Dynamics and Earthquake Engineering, 2008
In this work we investigate the application of the wavelet analysis to improve the well-known horizontal to vertical spectral ratio (HVSR) technique for site effect estimation. Wavelet analysis has been widely used in the last decade for its capacity to localise the signal in both the time and frequency domains.

Soil site characterization of Rabigh city, western Saudi Arabia coastal plain, using HVSR and HVSR inversion techniques

Arabian Journal of Geosciences, 2020
Rabigh city located along the coastal plain of the Red Sea in western Saudi Arabia is economically significant. This pioneering study assesses the site characterization of Rabigh city based on integrated geological, geotechnical, and seismological data.

Seismostratigraphic Modeling Using Constrained HVSR Data

Proceedings, 2017
An application of HVSR inversion is presented in order to verify the effectiveness of this technique for purposes of reconstruction of the buried geological setting where stratigraphic constraints are available. Specifically, the reconstruction of the stratigraphy in the studied area has been obtained by a seismic-stratigraphic three-dimensional ...

The Microtremor HVSRs in the SW Korean Peninsula I: Characteristics of the HVSR Peak Frequency and Amplification

Journal of the Korean earth science society, 2010
Fifteen min-microtremor data sets were collected at 136 sites from a coastal area of Kunsan and 117 sites from an inland area of Jeonju located in SW Korea, and were analyzed for the HVSR (Horizontal to Vertical Spectral Ratio) of the sites. The microtremor spectra of the coastal area have stronger energy in the lower frequency range from 1-6 Hz than ...

Free and Improved Computer Codes For HVSR Processing and Inversions

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2018, 2018
The investigation of seismic ambient noise (microtremor) in spectral ratio form, known as HVSR, is extremely popular nowadays both to investigate large areas in a reduced amount of time, and to leverage a wider choice of low cost equipment. In general, measurements at multiple locations are collected to generate multiple HVSR curves which can ...

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).

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.
