Determining Soft Layer Thickness Using Ambient Seismic Noise Record Analysis in Kota Baru, South Lampung

Makara Journal of Science, 2019
The local site effect of an earthquake can be calculated through an analysis of short period ambient noise, known as microtremors. The fundamental frequency and amplification factors can be identified by analyzing microtremors using the Horizontal to ...

Potentials and pitfalls of permafrost active layer monitoring using the HVSR method: a case study in Svalbard [PDF]

Earth Surface Dynamics, 2019
Time-lapse monitoring of the subsurface using ambient seismic noise is a popular method in environmental seismology. We assess the reliability of the horizontal-to-vertical spectral ratio (HVSR) method for monitoring seasonal permafrost active layer ...

Struktur Bawah Permukaan Pantai Semarang berdasarkan Metode HVSR

INDONESIAN JOURNAL OF APPLIED PHYSICS, 2023
<p>The aim of this study was to obtain a profile for each depth of the subsurface structure of the Semarang coast based on microtremor data. The acquisition of 109 data points in this study was taken using a single-station microtremor tool in the coastal area of Semarang.

Contribution of HVSR measures for seismic microzonation studies

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.

Aplikasi Metode HVSR pada Perhitungan Faktor Amplifikasi Tanah di Kota Semarang

Media Komunikasi Teknik Sipil, 2015
The Horizontal-to-Vertical Spectral Ratio (HVSR) is a simple method for estimating the resonance frequency of sedimentary layers. This method can also be used for estimating the site amplification factor.

A WAVELET REPRESENTATION OF HVSR TECHNIQUE

Bulletin of the Geological Society of Greece, 2004
In order to evaluate eathquake site amplification characteristics, horizontal to vertical Fourier spectrum of microtremor has been widely used. As long as the Fourier transform (FT) cannot distinguish between stationary and non-stationary coefficients we cannot eliminate the contamination of microtremors signals from short period transients.
