“…Since the horizontal-to-vertical spectral ratio (HVSR) method was proposed by Nakamura (1989), many studies have proven that the method can be utilized to well identify the resonance frequency of the site or building (e. g., Guo et al, 2022;Stanko et al, 2016;Nath et al, 2005;Arai and Tokimatsu, 2004;Lermo and Chávez-García, 1993), which was calculated as…”

“…When dealing with the ambient noise, DA might be caused by many factors, such as the local geological setting or the sources of the ambient noise. For example, [41] observed the DA in the frequency band 0.15-0.6 Hz, finding that the location of the sources affects the polarization of the ambient noise [42].…”

Directional Amplification at Rock Sites in Fault Damage Zones

Site effects refer to the modification of ground shaking caused by the local geological conditions that can result in the strong amplification of ground motion. The best-known cause for site effects is the presence of superficial soft soil deposits, which are considered in seismic design codes of many countries through the use of scaling factors. Rock sites are assumed to show no local site amplification. However, even at rock sites, seismic waves can be locally amplified at frequencies of engineering interest, with larger motion along one site-specific azimuth on the horizontal plane (the so called “directional site resonance or amplification”). These effects have been related to the presence of large-scale open cracks or microcracks in different geological environments (faults, landslides, volcanic areas) everywhere with a common signature: maximum amplification occurs transverse to the predominant fracture strike. In this paper, we summarize our main results obtained in the last decade with regard to several fault zones with different kinematics, where ground motion is polarized (and amplified) perpendicularly to the predominant fracture field as an effect of the stiffness anisotropy. In order to give a further constraint, we also show some cases where the directional amplification effects were compared with the S-wave splitting analysis method.
