Reliable Fundamental Frequencies of Soils and Buildings Down to 0.1 Hz Obtained from Ambient Vibration Recordings with a 4.5-Hz Sensor

Autor: Bertrand Guillier, Jean-Luc Chatelain

Publikováno v: Seismological Research Letters. 84:199-209

One of the most widely used methods for site‐effect studies is based on ambient vibration recordings and the frequency peak obtained from the horizontal‐to‐vertical spectral ratio (HVSR; Nogoshi and Igarashi, 1970; Nakamura, 1989) (e.g., Fah et

The relationship between ambient vibration H/V and SH transfer function : some experimental results

Autor: Rabah Bensalem, El Hadi Oubaiche, Marc Wathelet, Abderrahmane Bouguern, Djamel Machane, Jean-Luc Chatelain, Mustapha Hellel

The horizontal‐to‐vertical spectral ratios (HVSRs) of ambient vibrations are commonly used to observe soil resonance frequencies, which are revealed by HVSR curve peaks. These resonances have been explained either in terms of S ‐wave transfer f

Experimental Relationship Between Ambient Vibration H/V Peak Amplitude and Shear-wave Velocity Contrast

Autor: Fatma Khaldaoui, Jean-Luc Chatelain, El Hadi Oubaiche, Mustapha Hellel, Djamel Machane, Rabah Bensalem, Abderrahmane Bouguern, Bertrand Guillier

Publikováno v: Seismological Research Letters. 83:1038-1046

Originally proposed by Nogoshi and Igarashi (1970, 1971), the ambient vibration H/V spectral ratio (HVSR) method consists of estimating the ratio between the Fourier amplitude spectra of the horizontal (H) to vertical (V) components of ambient noise

The high activity level of Hybrid Events (HE) detected beneath the Cayambe volcano since 1989 has been more thoroughly investigated with data from a temporary array. The unusual HE spectral content allows separating a high-frequency signal riding on
