Abstract The horizontal-to-vertical spectral ratio (HVSR) method based on ambient noise recordings is a popular and efficient approach to estimate the seismic site effect parameters. This method is sufficiently robust in determining the predominant frequency (f0) of the site, whereas its estimate of the amplification factor lacks consistency because ...

The application of HVSR microtremor survey method in Yüksekova (Hakkari) region, Eastern Turkey
Journal of African Earth Sciences, 2015Abstract The horizontal to vertical spectral ratios of microtremor (HVSR) analysis of Yuksekova and its surroundings is carried out using the results of field investigations, local soil conditions and seismotectonic features of the region. Soil-structure interaction is one of the most important reason for building damage ratio.

Combined Analysis of Ambient Vibration HVSR and Active MASW Method
Proceedings, 2014The well-known non-uniqueness inversion problems of dispersion curves as well as the reduced resolution at higher depths could be improved by performing a combined analysis of data sets of different types. In this study, Nakamura’s technique or HVSR technique was applied to several ambient vibration recordings performed at the surface of alluvium ...

— The seismic vulnerability of existing buildings is usually estimated according to procedures based on checklists of main structural features. The relationship with damage is then assessed using experience from past events. An approach used in seismology for the evaluation of site amplification, based on horizontal-to-vertical ratio of weak motion and

Near Surface Soil Characterisation by Passive Ambient Noise HVSR Method
Soil Dynamics and Earthquake Engineering, 2010This paper discusses the use of the passive horizontal-to-vertical spectral ratio (HVSR) ambient noise method for near surface characterisation of the soil layers at a proposed building site. The uniqueness of the HVSR method is in having no need for any external excitation sources and cabling, and the setting up time is also very short.

Polarization analysis in the stationary wavelet packet domain: Application to HVSR method
Soil Dynamics and Earthquake Engineering, 2012Abstract Microzonation studies using ambient noise measurements have become very popular in the last years for local soil characteristics determination. For defining the capabilities of the ambient noise based methods, a physical understanding of the nature of noise is essential.

Seismic response and vulnerability of historical Trakošćan Castle, Croatia using HVSR method
Environmental Earth Sciences, 2016The Trakošćan Castle was built on the rocky peak of the hill in the thirteenth century. Castle structure has weakened with time, wars, inappropriate protection, and earthquakes. On 16 March 1982, the Tower Castle and part of second floor were damaged by an earthquake (M L = 4.5) with an epicenter 20 km distance from Mt. Ivančica.

Summary Seismic response characteristics of structures can be estimated by spectral ratios of microtremors measured on structures and their foundation ground surface. The microtremor horizontal-to-vertical-spectral-ratio (HVSR) technique has received great attention from all over the world with its simplicity together with quick information about ...

Site Classification of Kocaeli Region Based on HVSR Method
2019Seismic map of the world displays that Turkey is one of the earthquakes affected region due to active tectonic plates. In current research, one of the highest seismic alert zones of Turkey i.e. Kocaeli territory has been selected. The aim of this study is to classify the different sites of Kocaeli region depending on its predominant frequency ranges ...
