Improvement of HVSR technique by wavelet analysis
Soil Dynamics and Earthquake Engineering, 2008In 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.

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, 2018The 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 ...

Statistical Analysis of Noise Horizontal-to-Vertical Spectral Ratios (HVSR)
Bulletin of the Seismological Society of America, 2005Statistical 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 ...

Compaction evolution observed via the HVSR of microtremors
Géotechnique Letters, 2013The 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.

HVSR, Amplifications and ESAC: Some Clarifications
2020This 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).

Seismostratigraphic Modeling Using Constrained HVSR Data
Proceedings, 2017An 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 ...
