Estimation of glacier thicknesses and basal properties using the horizontal-to-vertical component spectral ratio (HVSR) technique from passive seismic data

Journal of Glaciology, 2017
Microtremor measurements and the horizontal-to-vertical spectral ratio (HVSR) technique, generally used for site effect studies as well as to determine the thickness of soft sedimentary layers, can effectively be ...

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

Near 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 ...

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

, 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 ...

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

Earthquake 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

Estimation of VS30 by the HVSR Method at a Site in the Kathmandu Valley, Nepal [PDF]

, 2019
The SAFER (Seismic Safety and Resilience of Schools in Nepal) project work package “New generation seismic hazard for Nepal” aims to produce relevant outcomes for earthquake engineers working in Nepal. In order to improve disaster risk management, enhanced seismic hazard assessment is needed.

Estimating site amplification variability in Yangon, Myanmar, from a dense nodal seismic array

Earthquake Spectra, Volume 41, Issue 4, Page 3168-3189, November 2025.
We explore a novel acquisition geometry that can be used to estimate the linear component of site amplification using a dense nodal seismic network installed in Yangon, Myanmar’s largest city. The city is surrounded by several seismically active faults, including the Sagaing Fault, which is capable of generating Mw > 7.0 earthquakes.

1D and 2D site amplification effects at Tarcento (Friuli, NE Italy), 30years later [PDF]

, 2018
A temporary accelerometer network has been installed in Tarcento (Friuli, NE Italy), a small town heavily hit by the 1976-1977 Friuli earthquake sequence, as a part of an ongoing research project aimed at ground motion simulation and generation of ...

On the behavior of site effects in central Mexico (the Mexican volcanic belt – MVB), based on records of shallow earthquakes that occurred in the zone between 1998 and 2011 [PDF]

, 2014
The Mexican volcanic belt (MVB) is a seismogenic zone that transects the central part of Mexico with an east–west orientation. The seismic risk and hazard of this seismogenic zone has not been studied in detail due to the scarcity of instrumental data as
