Procjena faktora poboljšanja tla primjenom MASW-a [PDF]

open access: yesEnvironmental Engineering - Inženjerstvo okoliša, 2018
U slučajevima temeljenja, u kojima vrijednosti slijeganja i računske otpornosti tla ne zadovoljavaju tražene kriterije, potrebno je poduzeti mjere kako bi se istedoveleunutar prihvatljivih granica. Jedna od metoda koje se primjenjuju u takvim slučajevima je poboljšanje tla izvedbom šljunčanih pilota.

Modelling the Importance of Ground and Strong‐Motion Variables on the Damage Status in the 2023 Kahramanmaraş Earthquakes Using Supervised Machine Learning

open access: yesGeoscience Data Journal, Volume 12, Issue 4, October 2025.
KNN achieved the highest performance (0.989) using the full dataset and 0.988 with ground‐based parameters. EBd and f0 were key contributors to damage, while PGA dominated strong‐motion models. Specificity consistently outperformed sensitivity in earthquake‐parameter models.

Evaluating Seismic Ambient Noise Techniques for Detecting Ice‐Bearing Rocks on the Moon

open access: yesEarth and Space Science, Volume 12, Issue 9, September 2025.
Abstract One of the primary objectives of upcoming lunar missions is to locate ice‐bearing rocks at the South Pole. While evidence for their presence exists, the exact distribution and quantity remain uncertain. In this study, we evaluate the potential of seismic ambient noise techniques—including seismic interferometry, H/V spectral ratios ...

Neural Machine Translation of Seismic Ambient Noise for Soil Nature and Water Saturation Characterization

open access: yesGeophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Soil nature and water saturation of the near‐surface directly influence land use resilience and sustainability in urban areas facing intense climate forcing and human activity. Seismic methods are widely applied in this context for subsurface characterization and monitoring, but often fall short in delivering joint geological, hydrogeological,

A frequency‐domain beamforming procedure for extracting Rayleigh wave attenuation coefficients and small‐strain damping ratio from 2D ambient noise array measurements

open access: yesEarthquake Spectra, Volume 41, Issue 2, Page 1333-1363, May 2025.
The small‐strain damping ratio plays a crucial role in assessing the response of soil deposits to earthquake‐induced ground motions and general dynamic loading. The damping ratio can theoretically be inverted for after extracting frequency‐dependent Rayleigh wave attenuation coefficients from wavefields collected during surface wave testing.

Valley of Mexico site response from non‐reference site approach

open access: yesEarthquake Spectra, Volume 41, Issue 2, Page 1029-1059, May 2025.
We present a model for Valley of Mexico site response that is referenced to a 30 m time‐averaged shear wave velocity (VS30) of 760 m/s. This reference condition ensures compatibility with regional ground motion models (GMM) for Central America and Mexico (CAM), which were developed from an expanded version of the NGA‐Subduction (NGA‐Sub) database as ...

Correlating Groundwater Level Fluctuations of a Fractured Confined Aquifer With Relative Variations in Seismic Velocity: A Way to Estimate the Groundwater Storage

open access: yesGeophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Analysis of ambient seismic noise is of increasing interest for its potential to monitor aquifers, seismic wave velocity being sensitive to fluctuations of the water table or to pore pressure variations. The correlation with groundwater pressure variations in confined aquifers, which are often strategic, is an open scientific question, as is ...

Geophysical imaging of the subsurface seismic structure of the Chestnut Hill Reservoir earth embankment dam (Massachusetts)

open access: yesNear Surface Geophysics, Volume 23, Issue 2, Page 105-120, April 2025.
Abstract Degradation within a manmade earth embankment structure is often unobservable from the surface. In order to evaluate the structural integrity of earth embankment levees and dams and identify subsurface zones of weakness that may result in the future failures of such structures, various geophysical methods have been proposed as effective ...

Influences of variations in the sledgehammer trajectory and collinearity of the geophone array in an MASW survey on the shear-wave velocity profile

open access: yesInternational Journal of Geo-Engineering, 2020
In professional activities aimed at seismic site classification, geophysical methods based on measurements of surface waves are often used to measure the shear-wave velocity (Vs), with the MASW survey being one of the most common techniques employed for ...

Multi‐Scale Geophysical Imaging of a Hydrothermal System in Yellowstone National Park, USA

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Little is known about the local plumbing systems that fuel Yellowstone's famous hot springs, geysers and mud pots. A multi‐method, multi‐scale geophysical investigation was carried out in the Obsidian Pool Thermal Area (OPTA) to: (a) delineate the lateral extent of the hydrothermal area and associated surface features; (b) estimate the ...
