Compaction evolution observed via the HVSR of microtremors

, 2013
The non-invasive measurement of horizontal to vertical spectral ratio (HVSR) of microtremors is proposed as a means to evaluate field compaction. The HVSR technique is a surface wave method that is quite distinct from the class of array-based surface ...

Investigation of the structure and dynamic response of granite weathering crust slopes based on microtremor recordings: A case study of a landslide in Lishui, Zhejiang Province

Zhongguo dizhi zaihai yu fangzhi xuebao
Granite weathering crust slopes are widely distributed in southeastern China and are highly susceptible to mass landslides during rainy events. Investigating the structure of granite weathering crust slopes and studying the dynamic responses of these ...

Inferring Cenozoic Cover Thickness and Bedrock Sedimentary Material in 3D From Geophysical Data Using Machine Learning Algorithms: A Case Study in the Lockington Region, Victoria, Australia

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This study presents a supervised machine learning approach to constructing a 3D geological model for the Lockington area in Victoria, Australia, by integrating borehole observations, geophysical surveys (magnetic, gravity, and radiometric), and elevation data.

Utilization of Spatially Distributed mHVSR to Assess the Effectiveness of Ground Response Analysis

Earthquake Spectra, Volume 42, Issue 1, February 2026.
One‐dimensional ground response analyses (GRAs) can introduce model error to site response estimates when wave propagation is not dominated by vertically propagating shear waves. We investigate whether the variability of spatially distributed microtremor‐based horizontal‐to‐vertical spectral ratios (mHVSR) is related to GRA effectiveness using data ...

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 ...

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
