Evaluation of a novel application of earthquake HVSR in site-specific amplification estimation

Soil Dynamics and Earthquake Engineering, 2020
Abstract Ground response analyses (GRA) model the vertical propagations of SH waves through flat-layered media (1DSH) and are widely carried out to evaluate local site effects in practice. Horizontal-to-vertical spectral ratio (HVSR) technique is a cost-effective approach to extract certain site-specific information, e.g., site fundamental frequency (

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.

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 ...
