Statistical Analysis of Noise Horizontal-to-Vertical Spectral Ratios (HVSR)

open access: yesBulletin of the Seismological Society of America, 2005
Statistical properties of the horizontal to vertical spectral ratios (hvsr) applied to noise recording are analyzed in order to define optimal strategies for numerical processing and identification of possible artifacts. To this purpose, two time series have been analyzed: one constituted by environmental seismic noise in the presence of a genuine ...

Simulating H/V spectral ratios (HVSR) of ambient vibrations: a comparison among numerical models

open access: yesGeophysical Journal International, 2023
The use of H/V spectral ratios (HVSR) of ambient vibrations to constrain the local seismo-stratigraphical configuration relies on numerical forward models able to connect observations with subsoil seismic properties.

Shear wave structure of a transect of the Los Angeles basin from multimode surface waves and H/V spectral ratio analysis [PDF]

open access: yes, 2020
We use broad-band stations of the ‘Los Angeles Syncline Seismic Interferometry Experiment’ (LASSIE) to perform a joint inversion of the Horizontal to Vertical spectral ratios (H/V) and multimode dispersion curves (phase and group velocity) for both ...

Shallow Shear‐Wave Reflection Surveys in the Wellington Central Business District

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Seismic reflection profiling using shear waves provides constraints on the thickness of sediments beneath the Wellington Central Business District. Standard seismic methods were modified for urban environments where limited grassed areas are available and levels of cultural noise are high.

Seismic site characterization in northeast India: a holistic GIS based approach

open access: yesGeomatics, Natural Hazards & Risk, 2022
The seismic site effect is critical in designing structures and the estimation of earthquake damage to existing structures, particularly in seismically active regions.

Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

open access: yesNear Surface Geophysics, Volume 24, Issue 1, Page 36-49, February 2026.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

Validating alternative methods to account for shallow site effects in hybrid broadband ground‐motion simulation of small‐magnitude earthquakes in New Zealand

open access: yesEarthquake Spectra, Volume 41, Issue 5, Page 3914-3948, December 2025.
Proper incorporation of shallow site effects in hybrid broadband ground‐motion simulation is essential to improving predictions at soil sites. This paper validates and compares four methods to account for these effects in the predominantly linear regime, using 1446 ground motions from 213 small‐magnitude earthquakes (3.5≤MW≤5.0) recorded at 38 sites in

Intelligent Diagnosis Method for Mechanical Faults of High-Voltage Shunt Reactors Based on Vibration Measurements

open access: yesMachines, 2022
Aiming at the difficulty of accurately identifying latent mechanical faults inside high-voltage shunt reactors (HVSRs), this paper proposes a new method for HVSR state feature extraction and intelligent diagnosis.
